Don - I suggest having your friend give Nick at AND Automotive a call. Nick's business is buying wrecked 107s and parting them out. He likely has what is needed and very likely the right color as well. He is located in Wilmington,CA near the LA harbor. (310)830-0604. If he doesn't have the door panels, there are a couple of sources for new covering and the masonite backing. Let me know if you need that info and I'll look it up. Do the seat bases have broken springs? I have a decent fix for that too as the spring bases for 107's are very expensive now.
