Mounting the M90 in a 900-series car:

If you had an AW70, AW71 or AW71L automatic gearbox to start with, then you can keep the transmission crossmember since that is the same p/n as the M90 crossmember. You will also need the mounting bracket for the M90 (number 16 in the last picture of gearbox parts) since that is not the same as the AW7x bracket. The crossmember from the AW7x gearbox is then moved forward in the car and mounted in the front threaded holes in the body a few inches in front of the AW7x holes (yes, there are pre-made holes for using the M90).

If you had a M46 or M47 manual gearbox to start with, then you have to get the AW7x/M90 crossmember.

You will of course need the center console trim for a manual gearbox (the M46 trim works although it is not the same as the M90 trim).
