You once said you were gonna use a white interior from a late-model car?
No harm is shopping for prices…
Since it looks like your car is gonna be done before Dick gets a start on his, he won’t be able to copy your car’s seat springs.
I loaned some of my bare seat springs to the man who started restoration on Tom’s car. He had someone cut down a HT seat back to fit his cvt.
Ok, Dug them out and took the pictures in my Garage. Hope they help!
If there is a particular angle or view of any of the two pieces, let me know and I will zoom in on that part.

Good memory Roger, My bride Pam, yesterday said what the heck get the interior done right! Love that Gal!
So out came all the interior pictures I took of other peoples Swivel seats cars and had an idea on what she wanted and explained it to my upholstery guy (sponsors our local Mopar clubs car show) And we will do a Belvedere Door panels and a type of pattern of a that I see on cars that looks like a SF seats but with out the Buckles, I will dig up that look on my Thread on my convert. Don’t want to intrude any further on Dick’s space.
John Q.
Compare John Q’s Picture #1, springset on the right,
with Dick’s Pic #21 of springset. There are differences. I hope they fit!
If John measures the overall length of the seat he has, and compares that to John’s, he’ll have a better idea of the chances.
I can’t recall now if any model’s seat bottom fits a cvt.
OK here is the tag info. I was in Hypoluxo, Fl about 15 miles south of me several months ago. There is a Car Museum there with a 59 Red SF Convertible that is absolutely Georgeous. I remember seeing a tag on the firewall but none on the cowl or door. There were two small holes on the cowl and mine has the two holes also, so I thought someone just moved the tag but apparently thats were it was supposed to be because I tried getting this one off. Took the screw out, stuck a knife under the botton to pry it off, bottom came up but the top has two small spot welds on each upper corner and it would not budge. I took a piece of paper and a pencil and made a shadow image as Roger suggested.
The 57/58 service manual on page 4 states: Body number location: The body number is stamped on a plate which is attached to the left side of the ENGINE SIDE of the dash. (I assume firewall).
See Picture: Seems to be a combination Vin/Data tag. Date: 0113
Serial: M255104283
Body: 255
Trim: 505
M255 Newark LP2N-1001
Paint: XX3 (XX is Iceberg White). What is the Three??
Other numbers: ???
Since I have a bolt of black and white upholstery cloth with a gold thread I will use it for the interior (it was in the trunk of my green SF when I got it, glad I didn’t put it on ebay). The vinyl parts of the seats and the door panels will be a slight off white if there is such a thing, to match the white in the cloth. I think black vinyl on the seats and door panels would be awful.
Since the factory color was Iceberg white that’s the color it will be painted. The Dash and garnish moulding will be either Jet Black or a dark grey to mach the grey that is also in the upholstery cloth. Black carpet, Black top. What chall think.
The seat springs I have is the rear stuck together, it will be a delicate operation to seperate them. Over the years they have siamezed together and are very fragel. (rusted and crumbly). Dont know if I will be able to save/use them. My parts car still has the back seat in it so maybe it can be modified to work. Thanks for the pictures John they will be a great help. I still going to try and find proper seats and that Cylinder cover if possible.
John - Ford Guys would never do such a thing. Now Chvey guys is another story.
John at Big M - Can you help???
Matthew - Those are some nice offers, sure wish you lived on the side of the pond. Please enlighten me/us with any more information you can glean from this tag.
Thanks,
Dick.
Okay then, I am satisfied it is the official tag.
Those of you who have received Build Sheets from Chrysler Historical can probably decipher the tag.
The Keijs gifted me a booklet which contains some order codes, so I will make some guesses here, guided by the booklet:
321=?
301= power steering
309= package including Sportdeck, side trim inserts, and two-tone paint.
Since it’s a convertible, I am guessing the top fabric color was the “3” seen in
the Paint code. I don’t know what color “3” is.
I used to have an interior color chart, but I think I sent it to the Keijs, along with a bunch of photos they are going to copy and then return to me. 
Your car obviously had a blue interior. Maybe “3” = blue.
292= Powerflite, but this car has TF button trim plate
Is this the 4, 283rd Belvie cvt made, John?
There is a blue over white SF cvt pictured in the Showcase.
Black over white with gold thread feature sounds nice, Dick!
Dick, if Matthew moves in with me, you are welcome to stop by and see him anytime! 
Dan
I guess the XX3 stands for Body: white / Insert: white (it had the sporttone inserts so this should be body color) and the 3 is for the cvt top.
Yours was scheduled on the 13th of January 1959.
I need to check some data plates to see if we can figure out more things.
Anyone got another plate like this? I have 3 over here, 2 that we got from Roger and 1 from the Fury but they are all different!
These are also mounted with 2 screws on the side while Dick’s data plate is mounted with 1 in the middle. Mystery!
Alright! After some research i can come up with this:
301 = Power steering
309 = Sport deck
321 = Convertible top color, Black
292 = Powerflite transmission
PNT = Paint, Iceberg white
Date = 13th of January
Serial = VIN
Body = 255, Belvedere convertible V8
TRM = Interior, brown seat with orange bolster
Roger: - It does have power steering. I think all 59 Plymouths, but I’m not sure, were all painted one color. Painted white tops, etc. were all done by owners. This was definately a 318 car, did they have powerflight on 318’s.
Dan - It’s a deal but only if he brings all, I said, all his extra 59 parts with him.
Matthew - That was quick, I have two Torqueflite transmission, so it will get one of them, I thought Powerflite trannys were only on 6 cyl engines. Brown and Orange, UGH, It’s going to be black & White. Whats a bolster. What about production number.
Dick.
I forgot, I don’t know if Belvedere’s had dash pads but this one is going to get a black one.
Dick.
You have to change the 292 to 293 then! It’s funny as for the body type order number 292 was for a Sport Fury hardtop.
The powerflite was availble on the 318 and had a standard axle ratio of 3.31 and the 3.91 was an option (option code 537 and it is recommended for mountainous areas).
Torqueflite on the 318 had a standard axle ratio of 2.93 with the 3.31 as an option
The brown and orange interior was only for the Belv cvt. You could get other but the colors are the same for a Custom Suburban.
They are:
Blue - blue
green - green
gray - gray
gray - red
Dash pads were an option on all models except Sport Fury. They were standard for that one 
Any chance your other 59’s have these plates for decoding?
Don’t know, will look tomorrow, time for my power nap now.
Dick.
Dick,
The options booklet in the gallery shows two tone as a factory option Value Story and Options List - 6~0 - 1959 Plymouth Gallery

Nice research, Matthew!
Now I remember…‘bolster’ is the second color in a two-tone interior. I think it refers to the vinyl, because the fabric was brown. I once had a '59 Sport Sub (equivalent to Belvedere) with the brown/orange combo and swivel seats…the colors were not too terrible. It looked a little Halloween-ish. I bought exact replacement covers from OAI and re-covered one seat, before selling the whole shebang to Ken in Las Vegas. The car had a brown dashpad.
There used to be a '57 Plymouth 2ht in Seattle which was black with white spears and top, and B/W interior. It was a nice car, but a little bland for me…I like some of the “that’s So Fifties!” color combos.
I disagree with the statement “all 59s were solid color, white tops added later by owner”.
Go to Gallery, options booklet for proof.
I said I wasn’t sure about two tones, I stand corrected.
Dick.
“Is this the 4, 283rd Belvie cvt made, John?”
This number in the VIN stands for the consecutive run of cars at that particular plant regardless of the body style (2door/4 door/wagons/converts) if made at that plant. Not all plants built all platforms or body styles. So it essentially is the 283rd frame bodied car that went down the line at that plant.
Model year begins with 100001 sequential number and ends when it ends on the last day of production of that model year for that car line. Then it starts anew with a new model year sequence at that specific plant. All plants have a 100001 start point.
This is the first one of my short 59 experience of a non-Evansiville built convert car being at the M-255 plant. I had thought that converts had all been built in Evansville and no where else. They built so few Plymouoth converts that I believed they were concentrated at one plant for production.
Now… I must rethink that. 
John
My apologies again, Dick. I tend to read the posts too quickly, and thought you had said “No” to the 2-tone option being offered.
I like seeing the 2-tone cars, esp. the reverse-of-typical…for example, a red roof on a white 4-dr HT.
I have a little time before the work begins in February. I can loan out the springs for a quick look and copy if it can be done in a couple weeks or so. No problem with that if he has someone to do the copying or duplicating set up to do so.
John Q.
Ok…With Tape measure…Will measure!
The verticle part of the rear convertible seat frame is 54.75" wide measured from the widest point of the base (near the interior floor of car) of this vertical part.
Top part of this the vertical rear seat at the top part, is 42.25" wide
The top part of this same vertical part is is 49" tall from the bottom of the rear part of the frame to the top of the rear part of the frame (area that rest against the pump supports cross member)
The base of this vertical part at the base is 5" thick (front to back) and the top part of this part is 4" thick (front to back)
i will try to do some sketching for future needs of Vert owners.
Hope you understand the measuring points.
John Q.
