Oh no. I don't have anywhere NEAR that ego. LOL I just threw out there how they came. I'm working on A body 10 X 1 3/4 brakes right now on a modified Ford 9". 1 3/4 backing plates and brakes all from an A body. As far as I know, that's all the A bodies came with, was 1 3/4 wide shoes. To my limited knowledge, the 2.5" shoes were b body stuff. I'm sure one of these guys will correct me if I am mistaken.....and that happens a lot.
