Just checked at work
Part number for a 1991 is 701 831 056 H
Part number for a 2001 is 7D0 831 056 C
The 1st part of the number 701/7DO determines the body code so in my opinion no it wont fit but couldnt say excactly why.
Hope this helps
If it helps more.... the part numbers change in 1996, a 96 van could have an early or late door depending on its chassis number so if your van is a 2001 u need get a door of a 1997 or newer to be sure. Dont think the longnose / shortnose makes any difference T:
