You like biting off big chunks at a time I can see.
Maybe change your handle to Boltcrazy.

I have replaced a front cowl as well as the dash with new panels. It was a lot of work! The parts did not fit like a glove. I still have my fingers and toes crossed that the glass will fit the holes.
You are talking about removing all but a few feet of the entire windshield openings with aftermarket panels.
You will require more than wishes for good luck from me. You will need a lot of skill and a lot of patience.
