Yeah no one's going to sell headlight replacements parts outside of OEM HID Ballasts, bulbs, and wiring harnesses. In your case you're in for a complete new assembly. You're only bet is to possibly find an OEM headlight housing that has broken mounting tabs or is damaged in some other area but has a good headlight lense and you can do the swap yourself.
But that is a huge PITA, I've done headlight retrofits before with GM SUV's and they are not the easiest headlights to disassemble especially compared to headlights from the import auto mfg's.
Good luck...
