In one of my Mopar books it says “Powerflite automatic transmission was optional with all but Golden Commando V-8”. Soooo, if pictured car has a Golden Commando with a powerflite, something is amiss. Maybe car originally came with a 318/powerflite and was later changed to a 361. I know a local fellow here that has an original SF convert, 318, with a powerflite tranny.
In one of the engine pictures, do you see what appears to be a little plastic bottle next to the brake booster? I’ve seen one of these on one other car. I think its a “secondary” resevoir with hose attached to the master cylinder. This makes it easy to maintain your brake fluid level.
