I have a 34 Ply Street Rod with a 360 Mopar. I have oil leaking at the rear main bearing/oil pan area. I can get at the lower enging and oil pan easily. I don't know if I need to change the rear main seal along with the oil pan gasket. The engine was rebuilt and put in the car for about 10 yrs. ago. I'm just wondering how difficult it is to change the upper rear seal. If I was sure a new oil pan gasket would correct the leak, I would do only that, but I don't want to do this twice. Any info will be greatly appreciated, thanks. Bob
