I need to find out if the caliper brackets that fit 12' brakes are the same size as those that go on 11" brakes. I am doing a disc brake swap and got a set of spindles from a 75 marquis that I believe from my research came with 12" brakes.I later found some brackets at a pick n pull but they were from an 11" car and they wouldn't clear the 12" discs.I am trying to figure out if I am doing something wrong or just need to keep searching for different brackets.
