"cut and retain all the rear windows" doesn't make sense. All the glass has to come out no matter how the job gets done.
Are you saying "chop the top" like on a deuce coupe? Cuz that ain't happening.
The 87 roof cutoff I have was cut as low as possible at the bottom of the pillars to allow it to be cut down and matched up to wherever I wound up cutting the pillars on the old one so the door opening and front/ back window opening can be properly matched up.

I saw your post about the possibility of doing this job on a ramcharger in another forum... Have you made any headway with that project?

I have taken the cab I have at home by the body shop and they don't want to do the work that I already have on the first cab to this one which includes transferring the wide transmission tunnel from that cab to this one. They want me to do that.... Id rather do things like floor pan work that is easier to hide with carpet seats and such
