Take off the nut on the back side of the backing plate. The socket size of the nut in the late eighties models was 7/16".(IIRC)

OK that's what I feared. The rust is so bad I couldn't identify it as a nut. Also no bolt head or anything to hold it on the brake side?

I'm working on mine today. I just got done ordering parts from Rock Auto. I just removed that from 1 side of mine. Like the other guy said. 7/16" nut on the back side. 2 - 1/2" bolts for the wheel cylinders. 7/16" line wrench for line.
I have dreaded doing mine but they were really over due for service. One side shoes were cracking other side oil soaked seal leaked from too much hub bearing end play I suspect. Any words of wisdom on setting up the bearing end play ?

Sorry, can't help you with end play. I'm slightly over my skill level on this project but am getting otjt!!

The bolt has serrations that hold it from turning. Worst case senerio is a vise-grip wrench to hold it if need be.

I always set those rear bearings with some pre-load. I just went and clamped my torque wrench in a vise to see approx. how much I would set them by feel. It seems like a torque of 15-20 ftlbs is about it. After assembly I crank them down to say 25-30 and spin them a couple turns to set the bearings. Then back off loose again turn the hub a bit to free the bearings from their tapers. Then snug it down to the 15-20 give the hub a spin to double check all is well. Now if this has the nylon lock type nuts you'll have to add to that torque for the ny-loc drag. I always did it by feel no torque wrench. Some grease on the bearings packed between 3-4 rollers 3-4 spots around need some lube on them until the rear gear oil makes its way out there. Some guy put a tablespoon or so of gear oil in the hub between the bearings but I never did. Just didn't like the chance of it getting in the brakes during assembly.

When you put it back together, the arm will not move if you get it too tight(self locking nut)
