Eagle 1660 Report post Posted November 17, 2007 Hi Just brought my first E30(NZ '89 325i manual) which has the analog clock, was just wondering if you can drop in a full obc with out to much hassle like the E34's?. Also where abouts is the diff ratio number on the diff?, i cant seem to find any tags etc just what looks like a part number. Cheers Quote Share this post Link to post Share on other sites
