i just ripped off the old upholstry,bought the same thickness wood at homedepot layed the old doorpanel on top, traced it out,cut it then glued the two pieces together,bought some fabric and 3m spray adhesive,sprayed the wood and fabric let dry for a min or two then worked my way from the middle out and stretched it around the sides and stapled the back..also make sure u only cut the holes for the window crank and door pull,unless u still want the armrest..

may i know the steps to your door panel fabrication?
