1970 International 4x4 Pickup

I had an uneven number of projects here, so to even it out I picked up another. This is a 1970 International Harvester 1200D 4x4 pickup. Its been sitting for a while and gone through a few owners during that time, so I really don't know much about the history of it. In this video I learn a bit about it and get it yard driving. I'm surprised by a few things, including a 5-speed overdrive transmission with a really weird shift pattern.
