i ran a 5mge flywheel on my 7m a few years back, its pretty well the same, but the pressure plates are weaker on the 5mge. and yesw as cre said none of the gte products will work with a N/A.
also beware that the older w58s shifters are in a slightly different spot.
be sure to buy a brand new master and slave clutch cylinders as they are WORTH the money.
and dont forget to search the forum for 5 speed swaps there is LOTS of great info around here, just gotta search.
