When replacing the rear main seal, how important is it to replace the cover gasket too? I see oil at the bottom of the seal but everything around the cover looks good. Also, how hard is it to remove the rear main with the plate still in the car? Any good techniques?
For about $50 you can get a new rear cover with a gasket and the rear main seal already installed. That's what I did and it was a lot easier than trying to get out the old seal and then getting the new one in. Just put a dab of rtv where the cover meets the oil pan.
Also to change the cover in the car is a bit of a PITA. you'll want to remove the bellhousing. That is after you remove the rear cradle, diff, trans, and torque tube. It's a good weekend by yourself if your good with a wrench.

Yeah, everything is already removed(currently replacing some differential components) except for the bell housing. The bolts don't look like they are easy to get to. I guess I'll roll back under the car on wednesday and see if I can get to those bolts. What brand cover/seal did you go with?
There's the new one installed. In fact I wasn't able to completely remove the bellhousing. I removed all the bolts but one I had to back off as much as I could then just pulled the housing back.

I would do the rear cover gasket and main seal regardless if they were leaking or not just for cheap insurance if the drivetrain was out for whatever reason... no sense in buying a new rear cover in my opinion, I just bought the rear cover alignment tool from saccity corvette along with a new rear main seal and cover gasket... those cover alignment tools work like a charm and I haven't had any front or rear main/cover gasket leaks since using them
