I also put an add on the moparts site, and one guy knew the awnser, though he didn't have a picture.
The standard window is used on the standard track. the black plastic thingy that attaches the regulator to the window bracket is maintained except for the regulator offcourse, the white two piece slider is replaced by a bolt and washer to secure the window in the top position.
This makes sense to me, so I think I'll try it this way.
If anyone would like to see a pic of the result I can post them here.
