Are the side windows not flat? Those can be cut using safety glass. If you cut the roof and able to lay the back window down then have someone cut the windshield down. You'd be off to the races.
When my buddy chopped his C-10 he lowered the cowl panel too so the windshield didnt have to be cut. He never finished it due to cracking his head open in a motorcycle wreck. No helmet. turned him into a vegetable.
