Hi Dan,

I'm sorry to hear the rear main is leaking. I installed a new rear main seal, just as you described above, when I restored that truck. I can't remember if I installed an offset seal in it, or not.

You might consider raising the engine just enough to pull the engine crossmember out. The crossmember is easy to remove and it'll make getting the pan in/out a lot easier.

If you do decide to raise the engine, be cautious of the upper radiator hose. The rubber on both ends of that steel upper rad hose is pretty stout and may not provide enough flex, which could possibly damage the rad upper house outlet.

There's also conflicting opinions on using a small smear of RTV on the seal halves where they meet. I've always done it this way with success... until your truck... sorry.
