8 3/4 axle shaft seals

Yeah pvc does work good. I've used it too. I don't think I'd trust the adjuster plate if it's warped. Bad thing is you have to remove the bearing to get it off though. But better to do that then have another problem. There should be steel shims/seals between the backing plates and the housing ends so they may be there and you just didn't see them. If there not there I think you can get them at NAPA. Maybe even O'Reilly's or Autozone if you find a decent parts guy.

Oh yeah. Don't sell them 741's short. They'll take alot more abuse than alot of guys think.
