I use the iron masters.I get 70 C body either drum/drum or disc/drum.They bolt right up.My 65 I had A body spindles.I changed to the taller late B body ones.Car handles great and has manual discs.Stop great even at 120 at the track.The drum master should have a residual valve in both ports.Disc only has one for rears.A body discs along with Volarie,Aspen IIRC magnum etc will also fit.They have the taller spindles which are about 1/2 inch or so.My 65 got the alingnment in better with tall knuckles.Rocky
