3 point seatbelts

Anyone have a picture or two of the belt system in a 70 Duster with that extra belt mounted to the roof ??

I took the belts out (except for the roof one) years ago when I gutted the interior, and damned if I can remember how they go back in .. I have all the parts, and I remember using them way back when, but old age is setting in and have a case of CRS disease these days !!

Thanks

Kenny
