Anyone have this happen before. The little plastic bracket that the driver side seatbelt runs through off of the drivers side headreat...it cracked right off.....damn fat chicks! Now, where can I find a replacement...junkyard right? But how do you repalce it. Where does the seatbelt detach so I can remove the old cracked loop and install the new one?
Help is appreciated, a spare part would be awsome if someone had one.
Thanks
