Yikes!! It's time for the "big cut!!!" The canopy comes as one large, over sized piece. It must be placed, marked, and cut to fit. The first thing to do is cut the excess mold flanges off of the sides to practice up your cutting and praying. Then it must be placed in the exact proper position, marked, and then the canopy must be cut in two. Or at least in about 3/4's and 1/4's. The smaller forward piece become the fixed windshield and the larger aft piece is further trimmed (a lot!!) to become the sliding canopy. It actually went pretty well, but I was really tense about splitting or crack that expensive piece of plastic, for sure!
