1923 Buick pads fit like they were made for them. They just look different. You can get them from Rock Auto, part number CB13. Peterbilt pads are supposed to fit, too, but I can't confirm that. I think part number 06-00754 is what is supposed to fit. I'm actually considering re-shaping the metal plates to Chevy dimensions just so I can have nice reproduction parts any time I need them. Plus, I can get the stainless dress up kit for them. Try finding a set of those for a Dodge.
