I finally decided to clean up the 91' IROC Daytona A543:
I'm in the middle of putting new seals in it, so I removed the differential bearing retainer on the drivers side. It came out pretty easy but upon removing the oil seal, I damaged the oil baffle dispite the FSM's advice not to. I also noticed there wasn't a shim in there either. So, now I need a new oil baffle, dealer or junkyard I assume?
I also want to replace the extension housing gaskets and seal too.
