The rear main can be replaced just by dropping the oil pan. While your in there is a good time to check the bearings and timing chain. It's a pretty easy fix.
Good luck!

-And replace the oil pump, clean/replace the pickup, and find out why you don't use silicone gasket sealer.

A little gasket sealer on the pan gasket is alright, just dont' get carried away or sloppy. You don't want to use it on the oil pump gasket!!

rear main seal

I saw a 302 that failed (locked up the oil pump) caused by a bit of permatex form a gasket I estimated to be less than 1/32" dia broke off a pickup tube flange gasket. I use very little gasket sealer. I let the gaskets do their intended function. I do use some grease on some gaskets to get them to release easier. I also use adhesive to retain the gaskets for assy.

For a pan if it is in good shape and you get the flanges real clean you can use a little silicone form a gasket without a gasket at all. It will prevent anyone from messing up your pan seal by tightening the bolts. For small blocks you can get a nice high $$ silicone gasket with metal inserts that works great.
