Disc brake conversion
I used SSBC on my '71 Dart GT.
My car had the 5 on 4" small bolt pattern HD 10" front drums. My car also has the factory installed a-body 8 3/4" 741 case rear end that I didn't want, or need, to change.
I was able to keep the factory 14" X 5 1/2" Rallye wheels which clear the SSBC brakes perfectly.
However, factory 14" X 5 1/2" STEEL wheels did NOT fit/clear on my car (so much for body color steelies & red line dog dish caps).
SSBC wasn't cheap, but it was a complete kit. I would use them again.
