Im swapping the stock drum breaks on the 72 scamp to a set of 4 inch Kelsy Hayes disks. Can I use the stock upper and lower A-arms that came with the drums? I mocked it up useing the drum A-arms and the disk lower balljoints and it looks like it clears everything.
I also want to order a rebuild kit for the suspension would this kit work with the drum arms and the KH disks?
Swapping to the KH 4-piston setup you can keep your drum upper control arms, but you want to use the disc lower ball joints because they are bigger than the drum ones.
I don't know anything about the kit you've mentioned.
I just put the KH discs (from a 70 dart) on my '65 Barracuda last winter. They are great! The hardest part was fiddling with the brake lines, had to make a couple of new ones and had to put a proportioning valve inline on the rear. There's lots of info about this swap, including this stuff right here:
