Most kits require the sealed green wheel bearings and the big bolt pattern. I haven't found one that will work with the OEM adjustable wheel bearings and SBP wheels.
back in 68 I had a new 68 fastback,383 form.s. was stationed at tinker a.f.b. in okc.on the way to work one morning, the shortest mini-skirt I`ve ever seen was walking down the side walk.going the same direction, the guy infront of me stopped in the middle of the street stairing(she was bootiful) "stacked", I was gaulking like the young horny boy that I was.looked up as i was about to hit him-panic stop! the front stayed straight, the back locked up and came around to the right(slope on the road)didn`t make contact, less than an inch between us! made a beleiver out of me on disc brakes!-----bob:coffee2:
