Does anyone know if a E36 compact 1.9 diff will fit a E30.
Thanks. Mark.

Yes, it will be a small case variety with a ratio of about 3.38.

Not 100% sure on the output flanges though.

I'm hoping to fit it to my 318is which has now got a E36 325 in it because with the original diff 1st gear is pointless.
Thanks.

Nice quiet diff.
