Just recieved my new plexiglass (maybe lexan) windshields from Custom Mold & tint. They look awesome, but didn't come with any instructions. The outer edges actually are not molded flat, kinda warp upwards. I need them to actually bend downward on the gunnels. Should I heat them up to form them better? Or if I drill the holes, and screw them down, will they form on their own, or crack? I've emailed CM&T and sent pictures, but have not recieved any support. I'm just leary of cracking them. Not affraid to try anything, just need some reassurance. Ranger 375V 1981. Thanks for reading this!
