My situation probably no longer applies. I got my B-body set about 10 years ago. I know they've changed things since then, but I had to do some machine work to make everything fit. I wasn't too pleased with the brackets right out of the box.

However, once that was taken care of they're a very cost effective alternative for a driver, and I'm sure they're fit has gotten better in the last 10 years.

My kit used late 90's GM truck calipers with early 70's Fury rotors.
