How difficult is it to replace the rear main seal? I watched a video on how to do it, and the engine has to be pulled, but I also asked Firestone, and they said it doesn't have to be pulled. I want to be sure that if i don't have to pull it, I don't do more than i need.

And as far as resetting the clutch for the manual transmission model, is it difficult to set it back in place? I swapped the engine not too long ago and that's the one thing I didn't do. A good buddy of mine who definitely knew what he was doing did it.
Thought I'd ask for yall's expertise! thanks in advance dudes and dudettes.
