Allen
Thanks for the advice. I have finally disassembled the problem areas of my
rearend, and yes you are very right, the rivets holding the backing plate on
are tough to get out. I had to grind the heads, then still had to drill them
out. Any ways its off and the search for another backing plate has started.
I was quite lucky inside the diff and all I found was a complete C clip in
the bottom of the diff. Somehow it managed to not go through any gears.
My question for you is, did you replace the center block in between the
axles? If so are they still available? I have been told that this block
starts to wear and that can be one reason why the C clip may have come out.

Blaine,
Sorry about your bad luck, but the same thing happened to me. To answer
your questions, yes, the C-clips are prone to failure so join the C-clip
failure club. No, there are not reproduction backing plates, so you'll need
to find one in a junk yard. The rivets are a bugger to get out, so be
patient or you'll warp the backing plate getting it off the axle housing.
Use grade 8 bolts to reattach. I was able to repair my backing plate with
some high strength steel and some very patient welding, but mine wasn't
damaged too badly.
Lastly, you will need to carefully pull the diff cover (obviously) and fish
out all the broken parts. Be surgically clean about this or left over
slivers of steel will trash your diff. Use NEW C-clips (they are still
avail) as take-offs have aged and will also be prone to near-future failure.
I hope that your axel was not bend or damaged in the detour it took in the
ditch. Take the time to put it on a lathe and check it. Clean it
thoroughly and look for cracks. You don't want to repeat this with a broken
axle. That also happens more than you might think. I've seen axle with
complete twists in them.
Hey, they things happen with old iron. Good luck with your fix.
Take care,
