I was under the impression that the 70 -73 SWB sub frames were shorter than the LWB sub frames.
However, looking about at realoem I see the same part number for the sub frame regardless whether it is a 72 /5 or a 75 /6.
Is there a difference in the sub frames?

This was on the BMWMOA site Jim. Hope it helps.
The difference is about an inch and a half. It is simple to see. If the flange that bolts to the rear end is welded to the swingarm at a short (inch and a half) cylindrical section, then it is LWB. If the flange is welded directly to where the swingarm flares out, then it is SWB.
