but i do not includ the hub or bearings, im talking about the hub housing it self, there are mk3 ones and mk3.5 ones.
i got one of a 1.1 once to replace a bad one on a mates FRST, no difference at all.
however bearing size does differ and so does outer cv joint size so the hub it self will poss differ on some models.
the hub housing on a mk3.5 is a little different, the bottom ball joint hole is a little bigger and i belive the hole for the shock is a little smaller
