That's exactly what I was looking into today.
Cleaning out the cab and starting disassembly, has shown up some more problems. The floor is badly rusted ( a 1" layer of silt and lots of animal waste) looks like something as big as a badger was living in it. One of the rear cab mounts was broken and the floor has a rip from the battery box to the rear corner.
The final straw was the inner rear cab panel (from the top of the seat to the headliner) has rusted through.
If I was going to replace that panel too, why wouldn't I just replace the one in the 3 window with a 5 window one?
That leaves the insets on the outside of the cab. Cut out the 5 window cab and stitch them into the 3 window cab? or buy the upper rear 5 window patch panel and do it neatly? or take the quarter window glass out, sell them and throw the 5 window cab away as originally planned?
Wish those dam windows didn't look so good.
