BTW, Glasstek f/g doors sell for $690 plus truck freight. I had a little over $800 in the pair shipped. Including all the parts (formed lexan windows, door striker latch kit, aircraft window latch kit, 12 10-32 rod ends, inside release handle, etc) I had over $1500 in parts. That doesn't count raw materials (4130 chromoly tube & plate) for building the window frames, inner latch rods, door striker (stock too short), and custom door hinges. Add to that 40 hours in fabrication time, so putting light weight doors on is no small project, nor is it cheap to do the job correctly.
Then came the carbon fiber sheet to make the door panels...
