I just bought a 62 cabover International that has the original spring suspension seat in it. I would imagine that the the same seat would have been offered in a GMC. The IHC has a totally different seat for the passenger. It is like a lawn chair and flops forward to expose a luggage compartment. My wife rode in that thing a lot of miles. And it was rough with a rubber pad Hendrickson suspension. When we first got CB radios, I called myself the "gunslinger in the Teddy Roosevelt Diesel car" because it was a rough rider.
