I've been trying to find some vacuum info on here, and noticed a lot of other people have as well. A lot of other threads have dead links, or just a "Go get a chilton's" responses. (Which IS what people should do!)
I thought I'd toss some info I've found out there so maybe some people have a single thread that might help them out, diagrams & all.
