your 5 speed will mate with your engine
you need to swap over the brake pedal as well it is easy.
clutch pedal is a serious pain though, do yourself a favor and take the seat out...
your auto car WILL have bolt holes for the clutch pedal. and a spot for the master cylinder.
sure your 7m clutch will do fine in your 5m. both non turbo 5m and 7m uses same transmissions w58.
i put a 5m clutch in a 7m before it roasted fast
