O.K. here's one more suggestion. Cut the windshield carefully. sand the edges and place in position. Keep one thumb over one bottom corner and drill a small hole in the other and into the fuselage. One small button head screw into the hole and tighten. Now press the windshield back into place and do the same on the other bottom / side corner. Check everything is equal and do the same at the middle / lower portion of the windshield. This one may end up on the hatch but it's easily removed if you need to get in there. You can follow up with a couple more button heads spaced between the three you just put in. Side windows? No problem if you cut them into 4 peices and not the two piece sets as they come. Trim all the plastic you can but leave a thin flange for the epoxy. One window, one fitting. 6 minute epoxy will do the trick if fitted correctly.
