Now I have found guys here on FABO that have said they used the 151 frame shoe and had satisfactory brakes. (151 is the Phord mud-stain 10x1 3/4 shoe. I haven’t tried it but seems promising. I have compared the 256 and the 151 and they seem to be identical. But appearances can be deceiving
Great info. Sadly I don't have a build sheet. I found a very small piece of it under the back seat, the rest is in some dead mouse. I can make out about half a dozen build codes, none seem to be brake related.
So it appears people questioning the car actually being a V8 commando were mistaken. There were 1965 V8's with nine inch brakes, and I think this is one of them. Here's a picture of the set up with just the top springs and hold down pins removed. Notice no push rods, (correct), and perhaps having no star wheel adjust would also be correct. No parking brake cable either, which would have attached to the star wheel adjuster. 1965 service manual shows all these items though, and the shoes on the car have more braking material than the shoes I bought. I bought 9x2 shoes from O'reilly. Says a "433 shoe". Would these be correct for a nine inch drum or do I need to go another direction?
