Ruff Stuff Specialties has pre-bent brackets and they are the only ones I will use, you can get them shipped to your door for $60. Use 14 bolt on your search, they also sell on ebay.

From the video it would appear that you could also do this same thing on the non floating 3/4 ton rear axel with all GM parts except the bracket. I noticed the end of the axel tube was 3/4 to 1" away from the bracket which would allow the rotor to sit farther in on the nonfloating axel and still leave enough room to work in a bracket and the caliper. Hub centers should be the same diameter, so I don't see why a rotor wouldn't just slide on like the drum would. I'm doing tire work on mine and I have some spare rotors so I'm going to look into this. Only problem I see right away is the emergency brake, but, Mico lock makes a fluid driven pressure holder that works like line lock for drag cars, but it's designed for tow trucks. I'll have to look into that also unless someone else beats me to it. I'm not real good with computers and such. Jim

14 Bolt Rear Disc Brake Conversion Kit, Weld On
You Are Bidding On Two Brackets

If you are skilled with a welder then this is THE best way to convert the mighty Chevy/GMC14 bolt FF/SF rear axle 1973-2000 from drum to disc. Its cheaper than a bolt-on setup, there are no spacers, nuts or bolts to worry about and its lightest way to do the conversion. Disc brakes are self cleaning and bring a weight savings of 50+ lbs, this is a fine upgrade for the off road enthusiast.
Plates are cnc machined out of 3/8” A36 steel. All the components we machine are drawn in 3d and programmed into the cnc machine using the latest cad/cam software. Ensuring the highest quality part possible, nothing is worse than getting ready to drop in an engine and not getting it to bolt up due to an inexperienced machine shop hand drilling your parts.

The vast majorities of you doing this conversion use the Chevy front calipers and cut out the cable e-brake system all together. If you want to keep your e-brake simply use '78 El Dorado rear calipers instead of the Chevy front calipers.

What else will you need?
All Parts Are Normally Kept In Stock At AutoZone and Advance Auto Parts Stores

(2) Rotors (1985 Chevy 3/4 ton truck front)
(2) Calipers (1985 Chevy 3/4 ton truck front)

Our conversion plates are then glass media bead blasted and powder coated. The brackets are then baked in the powder coating oven at 400 degrees for 20 minutes. The normal color used is jet black however if you would like your brackets powder coated a different color let me know and at no additional charge I will coat then in any color you would like.

If you are not a skilled welder and live in the Bay City, MI area and would like us to perform the installation of these brackets at our shop please send me a message and we can discuss the installation cost in more detail. We can also supply all of the parts needed to complete the conversion. When installation is done in our shop welding is preformed by a journeyman welder and inspected by a bachelor degreed welding engineer. The conversion can be done in about 2.5 hours while you wait.
