There is an angled bracket that fits in the top corner behind the door jamb with a captive nut that you fix the upper swivel fixing of the seat belt to... I think I may still have a pair of "unused" ones out in the garage if you are interested?
I have these brackets but am confused as to how to fit them to the upright. Anyone fitted them and if so how?
Just went and took this pic, it was pitch black so just had to point the camera and hope for the best!
Which bit can you not get to fit?
Umm, I think you might want to have a look at that image URL...
