E36 small case diff will not work. The mounting points are different. You need a small case out of an E30. With an E30 diff the cover will bolt up and you'll have to swap output flanges, then it should bolt up. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
