Swap in rear discs 70 Dart

I just went through this myself. Converted to BBP by purchasing Cass' axles. Was going to go rear disc but would have to buy his new brake lines & form/flare. Don't have the tools for that so went with the drum brakes (10x2.5) backing plate, shoes, and all hardware (bought on ebay). Existing master cylinder and brake lines did not need to be changed. Unlike the tapered bearings, I was a bit surprised that I had to drive the new axles in (could not push them in). Cass said to coat the outside of the bearing with some grease or diff fluid, then tap them in using a wood block and 2lb sledge. They popped right in. Since they are so tight fitting and have an o-ring on the bearings, should not have any more axle leaks.

When I converted to rear disks all I did was a little forming on the existing brake lines to fit them to the disks, worked fine. Granted they were lines that I made when I installed the B-body 8 3/4, but they used the same routing and length as factory. If they’d been original lines they probably couldn’t have handled the re-forming without kinking, but the new lines had no issues at all and the re-forming was pretty minor in my case.

I still prefer the tapered bearings. I’m not gonna argue the second generation green bearings don’t work, they work just fine. But I’d rather have the tapered bearings and heavy duty adjuster that DoctorDiff makes.
