All,
I have recently acquired a genuine Tilt frame for my Pickup, and I have all the correct "fitments", on the car to install it (At least I think I have). The "bars" bolt to brackets riveted on the back of the cab, and the hoops "push" into two holes along the top of the side of the load bay.
What stops the hoops pulling out of the load bay side walls. There does not appear to be anything that retains the hoops in the side holes.... (Schematic attached)
Regards
