Disc brake problem need help!

What kit did you buy? I converted my 1967 Barracuda to ā€˜73 up BBP using parts from a ā€˜75 Duster and Iā€™m running the 14ā€ Rallye rims with 225/60R14 tires with no issues.
It was a kit i got off of EBay my steel wheels are small bolt pattern they are 14 by 5.5 wide so the back space must not be enough it rubs on the inside of the rim along the front of the caliper. I read the install directions in small print at the bottom it says might not fit with some steel wheels and the small bolt pattern cragers. The whole set up may be a Chinese knock off. The set up i did on my 67 i piece meald it together from junkyard parts.
