I spotted a Gm 3speed with an R10 at the scrapyard. My truck has been converted to 12 volts and it is a 3/4 ton, so it has the open drive line. The scrapyard also had a couple Ford Trannies with the OD, pissibly T85 R11's, I'd have to go back and look. Is it possible to interchange parts with the R10 and R11s?
