This setup is on my coupe have used it for over 15,000 miles. This is on a 1957 Ford Rearend. Have this in my project journal thought I'd show it hear if any questions or comments. Total cost was around $100.
A friend had some brake brackets for 3 inch tube you can find them any where Speedway has them. I used Lincoln Verseai rotors,found at a swap meet, but I did find out 90 jeep rear waggoner rotors 3 inch tall,11 inch dia, 5 - 4 1/2 bolt pattern Car Quest p/n 5115 would also work. You might have to knotch brackets for small flange on calipers, also possibly open up opening more that goes onto axle tube to be sure brake pads are not sticking up above rotors. I used mid seventies gm front calipers I believe for a 76 impala. Put calipers together bolt to brackets and place over rotors. Put some lug nuts on studs to be sure rotors are on tight,also you might have to do some minor machining on inside of rotors to be sure rotors are flat against the axle. Apply some air pressure to caliper to firmly snug them to rotors and align up, tack in place release air pressure look everything over and rotate be sure everything turns ok and looks straight. I made some gussets and added them too. Be sure and put retainer bolts through axles flange in case can't get bolts in after welding,also placed some washers between axle flange and retainer to makeup space for backing plate. You also might have to put in longer wheels studs. Also used a brake fitting from Parts America or Advance Auto parts p/n 327853 7/16-20 to 3/16 hard line, be sure and use a copper washer I also used small amount of silicone pipe sealant. One thing to be aware of is the bleader vent for calipers be sure they are pointing up. I'm using manual brakes, had to use a small bore m/c to get enough pressure to stop good.
