The good thing in that switch isn't unique to the ST165. All Celica's equipped with power windows (which I think in the USDM, included all GT & GT-S models) had the same switch from 1988-1989. Also all Supras had them from 1989-1993. In fact, there was a very nice 1992 Supra in the salvage yard near me - not sure it is there anymore though. There were also some 88/89 Celica GT's there at one time - not sure if they are there anymore either. If that clip is a weak point on that driver window switch, it could be not many are intact anymore.
