The aftermarket dust shields I got for my 65 chevelle and 69 cutlass brake conversions worked fine. But, the aftermarket caliper brakets are another story. The bends are not smooth and therefore they will rub on stock SS 14 inch wheels. I had to grind and grind, and weld some tiny supports where I ground away metal to nothing to get my SS wheels, to work. But, with that elbow grease, all is fine now. If I had to do it again, I would look for used original A body caliper brackets. I used them on my 69 cutlass and the olds SS stock wheels (14 inch) fit fine. Aftermarket brakets should be fine for 15 inch wheels.
