Gotta be pulled. Some actually just move it forward out of it's mounts, and do it that way. That's crazy. Just scraping gasket pieces off under that condition would be torture for me. Pull it out all the way, and it's so much easier to do things out in the open. Not a bad job, if crawling around doesn't kill you !! It is getting to where I can hardly do that kind of work. Good luck and enjoy.
I would also mention the Dupli-Tech version of an exterior alternator install.
My experience with that project can be found in the reference section.
Either way you go, hoghideman, I would definitely do the alternator ipo replacing the stator. MHO.
