I used the ZF transmission, trans crossmember, shifter and driveshaft out of a wrecked 1997 328ic convertible, bolted up to a medium-case E28 differential. This all fit without modification and the shifter was centered in the console. I use E36 M3 motor mounts and stock rubber trans mounts; I originally used poly trans mounts, but it buzzed too much with my single-mass flywheel. I had to clearance the welded-in chassis brace to clear the differential (that could be your clunk) with a BFH, and I used poly bushings for the rear suspension crossmember to limit twist (and possible clunking, which happens slightly when in reverse). This was my setup with the M52, but when I swapped in the S52 I swapped in a Z3 shifter and it is still centered. __________________
