i too am in san diego, i have seen many doors in the wrecking yards near the border. haven't been there in a while, but there were alot in the past. send me the chassis number to my email and i will see which ones will fit.
who does your service? i work for a reputable shop here in san diego who still does work on the older models. let me know if your car needs any service.
