sunroof parts are insanely hard to find as you already know. I actually had a spare switch console but I sold to Killer RS on RSLC 2 years ago.
My car is possibly the only first gen turbo wagon with a sunroof in Perth (happy to be corrected) and one of only a few in australia... what I mean to say is, the local wrecker won't help you. You need to search Australia wide. Best of luck my friend!
