I think that the Mk. 1 window regulators are different, as are the latch and handles mechanisms. Vent windows are different too.
Oh, and I have all the pullhandle door stuff if you need it. Just a matter of finding a pair of both lefts and rights. Some things here are labeled as to which side, but most aren't. If I have to, I can go strip out another door and get some stuff that way.
