I went with the disc conversion from SSBC that does not require replacing spindles, yes they have these now, I went with their SS brake lines and fittings that fit perfectly, I used a booster and cylinder combo from Ames, noW HERE'S THE CATCH, you want the disc/drum proportioning valve from ClassicIndustries because it fits in the stock spot off the master cylinder and it fits the lines perfectly and it's pretuned and it works great. All my hardware and rebuild from parking brake and rear drums I got from Ames.
