OldIHC

back in 1975 my buddy drove his L-120 off a cliff, not a real tall one but a cliff non the less,

he showed me the truck in the wrecking yard, the engine & trans broke apart,

what I was most impressed by, was the bruise on his chest from the steering wheel, you could see the three diamond logo from the horn button!

Thanks for all the great input on this topic and for the seat belt hardware links. It will be on my to do list.
That's a good point made about collisions from behind and protecting your head from the cab.

Comes down to we are still at the mercy of the "Other" driver and that is the part that sucks, knowing all the distractions that are in vehicles these days.
