We installed power windows from a 2014 HZJ76 into my 79 series that had vent windows. Needed the metal channel at the bottom(shorter on vent window truck) of the window. 76 did not have quarter windows.
Power regulator bolted up no problem....holes were on the door of my truck. I think the doors on my Troopy had the same bolts as the 09 LC79's doors.
76 windows for sure won't fit on a Troopy....different(at the rear). 78 or 79 interchange from what I recall when we did new glass in my Troopy IF they have the same vent windows....or don't.
