Sorry for my lack of knowledge but I'm new to Alfa cars. I'm in the process of trying to purchase a 1991 west coast Alfa spider automatic and would like to know what the differences are between the power door mirrors on the 1991-1994 and the earlier cars. ( I know, the manual mirrors work!) A PO removed the original power door mirrors and replaced them with some manually operated mirrors. If I purchase this car, which I think I will, I would want to restore the mirrors back to the originals. I have no idea whether there was any difference between the earlier cars and the 91-94 models. Are these mirrors available either new or used, and from who?
