rear seat mounting points

[Hank70SS]

Shaun, once the seats are properly installed they're pretty secure. The seat back hangs on the hooks at the top of the metal trunk divider. Looking at the picture, note the 2 nuts welded into the trunk divider directly back from the hooks you're missing. 2 loops come down from the seat back and are bolted down to those nuts. The seat bottom slides in and the rear lip slides up behind the seat back. The front of the seat frame is locked into the 2 hooks. The back of the seat bottom can't come up because it's trapped under the seat back. It can't come forward because it's latched into the hooks. The seat back is secured because it's hanging on the hooks and bolted down at the bottom.

I'll see if I can get some usable measurements later.
