I have two complete trans and a bunch of parts. I bought out a trans shop when they went out of business. Bob has one, if he doesn't use it, that would be a 3rd possibility. Read thru my 200-R4 build, it's quite complete. They are getting hard to find, but they do have better gear ratios. The 700-R4 is easier to find, but like I said the ratios are not nearly as good. Especially between 1st and 2nd gear, it's a big jump.
