Fair price for front disc brake conversion

I used the SSBC kit on my '71 Dart GT. Very complete kit. Also allows either the 5 on 4" SBP or the 5 on 4 1/2" LBP wheels. I run 14" X 5 1/2" Rallyes with no clearance issues. Can't speak if Cragars will clear. I got my kit through Mancini Racing for ~$830 about 10 years ago.
