Bit of a strange Q but are the early 90's 1.6 and 1.8 diff casings the same size? my 3'' exhaust runs close to the 1.6 diff and im worried ill have trouble with clearance after fitting the 1.8.

I think both are same width ,but I could measure a 1.8 for you.Definitely 1.8 is longer and a shorter diveshaft also. We have both types if you do need anything.Robert 086 8226506
