This email came to me by way of the Plymouth Owner’s Club. I’ve copied John Q. on my reply - John’s less than two hours south of Kevin - but I’m also posting here for advice.

Hi Kevin, I live about 45 mins south of you in Arvada, Colo, I will dig up the link to what I did for my Belvedere Convertible for the front Disc brake Conversion. I did not convert the rear brakes so I don’t know what would work there.
As far as the Master Cylinder, I replaced the single chamber MC to a dual cylinder version using a 66 A body (Dart) Master Cylinder. I used F body (Volare/Aspen) spindles and the disc rotors from a 80 cordoba/Magnum (J Body) to keep it all Mopar . I just had to trim down the new tire rod ends a bit to make it all work. I used the booster that was already on my car. If yours was not already a power brake car you can get one of the original 59 Booster from Big M (John Fowlie) on this Forum. Other Mopar PB Booster may work but I just kept the one that I had.
I did buy a Mopar performance manual adjustable proportioning device but it worked well right out of the box so I have never had a need to adjust it at all in regards to front to rear percentages in braking power.
I will go thru some of my old posts to get you the link when I did this.

…and [go here](https://59plymouth.net/showcase/steinmaier/page3.html) for a somewhat dated, but also excellent discussion about how to install disk brakes, by Stefan Steinmaier. Again, it’s for the front only, but there’s still proportioning…
