The new top is made from the same mold as the first top, but reduced in height. Interior headroom is about 5' 8". It is much better proportioned than the top on the other boat, in which I could stand up straight (I'm 6'3"). Windows are on order from Wynne Enterprises.
And here are the roughed-in rear windows. I used 1/2" pvc board, which was MUCH cheaper ($100 for a 4X8 sheet) than Starboard, and also easier to work with. It can be glued, screwed, patched, and painted. In this situation, strength isn't really an issue.
