I started out to make some canvas half doors that resembled the oem soft doors but offered more protection off road. The tubing used is .120 wall 1” round and 1x3”. Once the lower frame was finished I thought about trying to graft the upper window portion of the oem soft doors onto the lower frames. After cutting and grinding a little I managed to get the upper and lower sections to fit into the door frame pretty well. I had to make some hinges due to the 1” round stock that I used which positioned the door more outboard than oem.
