Does anyone happen to know if early Coupe GT or 4k/4kq rear seatbelts will fit in an early ur q? What I need is black seat belts to replace the brown for my interior swap. I have '86 Coupe GT black belts, but they won't operate properly due to the different mounting arrangement in the early ur q. TIA!
