Order yourself a transmission mount from a 2.5 Z4 that came with this transmission and it then bolts right up. The driveshaft did have to be lengthened 100mm by a local driveshaft shop. I also had to have a custom length DSSR fabricated for the gear selector.

Humm, I always thought our cars come stock with the ZF GS6-37BZ, not a Getrag. What made you stay with a synchro box?
I am thinking of changing the stock H pattern 6-spd to a sequential dogbox with straight cut gears from Samsonas or Hollinger RD6.
H pattern synchro boxes are so slow; after you have driven a sequential you can never go back.
