I called him, nice guy. He said the ones I have from Dennis Carpenter, and likely the WH and TBP pads, are actually made for a 68/69 truck, not for a Bronco, and he doesn’t think the thinner correct pad is made new. The pad I have is 5/8 thick at the thick side, and it needs to be half that.
I guess I might have to figure out how to slice it in half.
