make them outta full doors! make masking tape "casts" off of another set of half doors. put on like 5 or 6 layers of tape and then trim them around the cut lines. Now CAREFULLY transfer them to the full doors, trace the lines with a sharpie, use a cut off wheel, cut long and grind back. read the instructions in the technical articles about the fulll top conversion and follow the instructions on the window channel brackets and door cap brackets. I did two doors in an afternoon and they came out perfect. I'm going to do another set of doors soon and will use this same technique. Don't be scared, there's a $hitload of doors out there so if you screw up...find another one.
