I have a HX panel van with side windows and a rusty roof and a WB windowless panel van with severe body damage down low but it has a good roof. I want to repair the HX as a windowless van and use the WB for parts only.

I was wondering if the experts here would have any tips on swapping the full turrets (roof and sides)? I can find the spot welds inside the back area and these could be cut out quite easily but what I cant determine is if there is a join is in the roof over the top of the cabin. Does anyone know if the roof is a full one piece all the way from the windscreen to the back or is the a join or seam somewhere? How does the roof join to the door frame (maybe in the gutter area)?

If anyone has a diagram of where the seams are I would really appreciate it. There was a picture in another thread but it is an old thread and the picture has disappeared.

Thanks.
