In Reply to: Larger differential cover, ALPINA? (more) posted by Terry on December 04, 2001 at 14:07:44:
Got the hole thing form Mitch Herman at Motorsportimports.com.
it was $150 and took about a hour to install. it does not hold any more oil but dow keep the diff cooler!
I know Alpina has an E36 rear differential cover available. I believe it holds almost one quart more oil AND it does have cooling fins.
Did Alpina ever make anything for the E30s? I'd imagine it would apply to all models of the E30.
Any leads or information, please let me know. Doesn't have to be Alpina
