Tranny needs to come out for the engine swap- Might as well do the tranny at the same time. Get a m5 guibo from a e34 and shorten your driveshaft 3.4 inches. You will need the 58mm bolts [6]. Make sure you get the hydraulic pipe from a later master cylinder to slave as the fittings are different. Best deal for clutch package is $228.00 with T.O. and pilot included. Done....about 600 bucks if you already have the tranny.
