I learned to drive a stick in a '68 IH. Looked just like yours, same color and all. I remember it have a weird displacement V8 (348?), big oil-bath air filter, and a crazy low 1st gear.
There is a crewcab 4WD version of yours here in Omaha, sitting in a farmer's treeline. I would love to get it and throw a Cummins in it.
