ASE lists driveshaft adapters in several bolt circle diameters and they are not interchangeable. This one is 105mm, for N54/N55 135i and 335i transmissions and B58-based 8HP units. The 96mm version covers E36, E46, Z3, six-cylinder E39 and B48-based 8HP50 transmissions. Measure your output flange bolt circle rather than going by chassis alone.
The adapter will not work with a stock driveshaft. It is designed for a one-piece shaft with 1310 or 1350 rear flanges. ASE can build a driveshaft to suit — steel or aluminum, both on 3" tube, or carbon, typically built in 2–3 days.
