I have a 63 C10 that I dropped back in 95,I got the 3" drop spindles, then went to the local parts store and bought brand new the roters, booster, calipers and shoes,proportining valve, and master cylinder for a 73 chevy. I believe my cost's back then where around $700.00. The draw back was no cores on the items I purchased.I also cut the coils in the back 4" to give it a nice stance. I've never been happier, the truck stops on a dime, and if you plan on dropping a 350 motor in like I did, then a disc brake system is a must. I don't think I have to tell you what happens when you drop a 350 crate motor in a truck that has drum brakes and a single resevoir master. The only draw back I've had, and I plan to fix after I get done with the body and interior, is the lower control arm ride height. It's not a pretty feeling when you go over a speed b ump, no matter what speed. I'll keep you guys posted on what I do and how far I get done on the body and cab floor, and I'll try to post pics too.
