The Kelsey-Hayes Disk Brake Swap Thread

Going from the 10's to a disk, the LBJ mounting holes just went from 1/2 to 9/16. I drilled my drum ones out and they worked perfectly. I had just bought them but they are probably the same price as the disk LBJ's. The later 5 on 4.5 stuff had the larger upper ball joint. Good point on the stock combo valve. I used one too after I couldnt find my Summit adustable. Made plumbing that much easier, just had to bend a few tubes to make it work and I think I needed 2 adapters.
