Pep boys actually sells a universal metric clutch alignment tool. Its like 19 bucks or some shit. I used it once when I was in a bind, it didn't have an exact fit but it was close enough and the tranny went right on. After that I took it back and told them it was shit..got my money back. I could easily eyeball one though. Just tighten down the bolts enough to where the disc is snug but can still be moved. Use something to basically measure it to get it even on all sides compared to the fingers on the diaphragm. The tranny will go on, then after that you have nothing to worry about. That or just go to pep boys and get that universal one.
