Hi are the gtb and gts doors shells interchangeable? I have a good set of gtb US spec doors I want to put on a gts. Sent from my iPhone using Tapatalk
They appear to be different. Looking at this parts diagram: DOORS - Ricambi America, Inc. It looks like part 79 is the door skin and the part number varies not just by side (sinistra/destra), but also by body style. This is for a carb car though, not sure which model you have and it's door may be identical by body style.
Possibly because of the window frame. The panel may have a different shape where the window frame is bolted to the door.
