Have you tried the junkyard searches like car-part.com, etc?
There's got a to be a few totaled models of your car out there waiting to have the ip pulled. I've also had luck finding a yard that lists another part for a car, then calling them and asking if they have the specific part I need. Sometimes these places don't list every single part on the car.
Good luck, 1200 to rebuild an IP sure is an investment.
