Sweet truck there. I don't know how you guys can deal with rust. I have forgotten most of what I knew about dealing with it and am quite content with that. Well, I guess not entirely forgotten, as when I was in WI this summer my cousin put me to work removing all the broken off, rusted-in-place bolt remnants in his John Deere 730 Diesel project. (Me): Uh, I'm on vacation pal. (Him): Here's what I got--get to work. I guess it just enhanced my disdain for it.
Anyways, keep in mind the Delco belts are not GM belts. They are a belt manufactured by someone (don't know who) to their own specs........
