Re: Disc Brake Upgrade Reference Thread

My dad just did this swap on a 64 c20 w 75 c20 parts. He wanted to keep the 8lug because he had nice wheels on the truck. He had to swap the whole xmember becaused the control arms didn't match up. Also, we found that using the 75 motor mounts pushed the engine about 2 inches forward of where it was originally. Other than that it was the easiest and most problem free part of the build.

will 80-87 3/4 ton or 1 ton trucks work for the conversions? What about 73-87 c20's also? As long as theyre 2wd? im assuming they would have the 1-1/4 rotors instead of light duty, right?

Im looking to swap to my 64 c10 6 lug - and keep 6 lug - i see the parts store call out for them (thanks) in one of the thread posts

a side question - ive got drop coils in my stock arms now - could I resue them? or are the 73-87 coils different for some reason? Can you run drop coils AND spindles?
