12 bolt disc brakes ?

Ive got an older version of a 12 bolt chevy, probably 70,s if it matters the time frame. I need to make it a disc set up. I was wondering what if any chevy factory 12 bolts had a disc that would fairly easily be swapped onto my current rear end ? I dont want to go the 1500.00 conversion kit if I do not need to.

any thing off a old trans am should work and they did put them on the back you can buy the steel bracket that you can weld on the rear and run the old GM single piston front caliper on the back and find a rotor to fit like a ford or gm car if you need E brake then look at the old trans am or buy a kit there is many out there

Thanks for the reply Pat, I will find me some used parts and consider that part done, at a price I can afford..

try hunting the junkyards for a '85-'90 iroc camero!
factory stock with disk brakes,they also have a pretty good parking brake setup!:D

Thanks Donnie I will make a note of that.

I used the disc brake set up off a 85 el drado cadallic they have a straight axle but the rear is the same as the trans am. they almost give them to me at the junk yard because they were off an odd ball. i made my bracket that bolts on to the rear end out of 1/4 inch plate. i have about 40,000 mile on them now.Attachment 33152 jonathan

I used front rotors that slip on the axle, with 1980 Monte carlo front calipers and fabricatad a 1/4" bracket to hold them. For a parking brake I used a valve that is mounted up through the floor, when you want to engage the parking brake, you push the footbrake, pull up on the valve, then release the footbrake and it holds the car. The disks really work well.
