Lot has been said on disc brake conversions . . . SO there is my two cents worth . . . I have used F,M,J body spindles, calipers, etc . . . on two different cars (one a C body, and one a B body) . . . fit perfect - just needed a washer on the lower balls joint to spindle bolts. Used the rear mount and PROPER calipers (believe they are mid 80's 5th Ave. calipers, with the bleed screw in upper location), stainless steel hoses from Dr. Diff, and voila . . . (of course new master cylinder) . . . both cars stop perfect, no issues on alignment or bump steer, etc . . . .

If you don't want to search for all separate parts, go to Dr. Diff. Knowledgeable, and reasonable and you will be happy with the service.

Cheers,
