'70 Dart 392 Project; what direction?

Does anyone have any recommendation on a rear disc kit? Since I"ll be narrowing my housing anyways I might get by with a less complicated kit rather than adapt the old drum brake flanges to disc brake?

Sorry, missed this question before.

I would look at Doctor Diff for a rear kit.

Brakes :: Rear

Should bolt right onto an 8.75 axle flange, lots of people have had good success with them. But only floating caliper kits (not sure if you want fixed multi-piston calipers or not).
