Inliners International Forums General Discussion Engines Rear Main Seal

My rear main seal is leaking, and I'm debating doing it myself, or having a shop do it. I have a '68 C10 with 250. Normally I would do this myself except you have to jack up the front of the motor in order to get the oil pan out. Any ideas on where to jack the motor up at? Will I have to drop the tranny(manual) in order to jack the motor up? I don't have an engine hoist. Also, I've looked at the Tech Tips section on the Stovebolt site and know how to do it. The only hitch is, I don't know which seal I have. Wick or neoprene. Any ideas? One other thing. I remeber that I had to fight to get the oil pan back on, because none of the bolts would line up right. Any special ways or steps to bolt the oil pan back up without moving the gasket. Thanks in advance. John.
