i appreciate that are you in Dfw?@Tom73 @Bigfx1 yes the parts can be ordered individually, and yes you can do just the one door. I used JScan to program mine, others have used the Tazer. The only way to tell is to open up the door panel and compare the part number or maybe look for wires in the #15 and 16 cavity in the door harness plug. Bigfx1 if you are near by I would be willing to help.
