After i purchased my 89 m3 i decided to replace the clutch. I purchased the auto specialty (part no.10-04015) and when i lined it up with the one i removed, the new one was smaller( it didnt line up to the flywheel).I figure could maybe the jerk i bought my baby off of have put a 325 clutch and flywheel in? Is the 5sp. trans the same too? I need help!
