Some of you may be interested in what I am currently working on for my 1936 1.5 ton axle.
I am using gm 6 lug components.. which is the same pattern as the old drums
I started with rotors from a escalade/tahoe..(they are 12" rotors) and turned the bore diameter from 3.125" to 3.8" this allowed the rotor to fit over the hub..

Then I picked up these massive calipers from a police addition tahoe... they are dual piston...
You can see in this shot that the rotor is bolted on as well

These brakes are going to be a necessity with the highway speeds I am planning.. some of you may remember the rear end conversion i did on my truck...
So far this brake conversion has been pretty painless..Ill keep you guys in the loop
