Thread: Fitting seatbelts in a 2A 1971 truck cab - again - please

You can try to get these brackets of a s3 tub. They mount to the floor and also have a bracket tbat attatches to the chassis underneath the tub as well to provide extra strength...



First pic is from underside of tub. Second pic is the extra stay bracket that attatches from one mount bolt to the chassis.
Hope this helps. If u look in the s3 parts book u can get a better idea.

Cheers Rod

Basically, the belt mounting bolt goes through the front section of the tub, between the forward wall of the tub and the upturned lip that the seat box is bolted to. Early mounts had a steel plate that spread the load over the underside of the join between the horizontal and vertical panels on the tub, but the later installation had a steel strap (about 25mm x 5mm) with a twist in it going back at about 45deg down to bolt to the chassis bracket.

The details probably varied over time and between countries - there are several variants shown in the optional equipment catalogue, and I believe there were others not shown.

Thanks, but I am not sure if I understand the word "tub". Could that be the "compartment" where the seats are mounted ?

Tub is the rear body of the vehicle where the load is carried. The front wall of it is the bottom half back wall of the passenger compartment, as is the lower sides behind the doors. This description is going to vary according to the type of body fitted, but I am assuming you have the standard One Ton body.


If you have the HCPU rear body, or a tray rear body, the tub as such does not exist, but in its place is a "tub" comprising just the lower part of the rear wall and sides of the passenger compartment, and if it is a station wagon, it has a tub, but the front wall only goes to up to the top of the seat box.

Thanks again, and sorry for maybe silly question. Here is the car:
