I swapped rears installing one with 3.08 gears and drum brakes and 5-lug hubs. I had to buy new wheels and I did the rear brakes as part of that project. When I saw your $400 figure at first I wondered what you were spending it all on, but I think I spent in that neighborhood on mine. For a while I ran with 6-lug wheels in the front and 5-lug in the rear.

Then some months later I had trouble with the front brakes and decided to upgrade to disk rather than repair. I bought a kit that used disks and calipers from the same car my rear had come from. I installed the disk kit and first time I applied the brakes the fronts froze and wouldn't turn.

Turns out I had a 10 lb residual valve built into the existing master and that was enough to prevent me from turning the disks by hand. I solved the problem by switching to a dual master and replumbing the entire system with the appropriate residual valves for front and rear.

If I were doing it again and wished to do it one piece at a time, I'd install the dual master (use a disk brake type) and replumb before installing the disk brakes.

If you stay with drums on the rear, I don't think it would matter what order you do that part in.

If you hunt around on my web site (www.OldSub.com) the whole story with more details are posted there. I've been driving mine for a couple years now with the new brakes and stuff and mostly I'm happy with it.
