You can use the gearbox from the 318ti on the M50. I don't see why the 318ti clutch wouldn't work for the M50 except that it is smaller than what would have come on a manual transmission 325is. I'd probably go for a new 325is clutch and flywheel just to know that stuff is new and won't need replacing again. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
