Yes, I agree, these parts are hard to get.
I'll try and get a mate to get them for me from New Zealand. I got these parts for the previous MR2 that I owned.
A friend on mine in NZ has a 1989 AW11 SC with retractable mirrors, and the mirrors I got for my NZ car (off a wrecked 89) were also electricably retractable.
_T_, when you wired up your '89 wing mirrors' did you not have the extra wires? Perhaps there are 3 versions of side mirrors? Of course you also need to add a 'mirror retract' switch .
Do you (or anyone) know of some other model Toyota wing mirrors that would fit the AW11?
