Freeing Jimmy - 1961 GMC K1500 Sitting for 15 Years - Will It Drive? (Part Two)

My father purchased this 1961 GMC K1500 4X4, known to everyone as "Jimmy", in the late 60's and mostly used it on the farm to haul things, pull a backhoe loaded on a trailer, and rescue folks who managed to get stuck in the mud. It had been running and drivable up until 2006 when it was parked. About a decade later I installed a new carburetor, coil, and electronic ignition module, but was never able to get it to move. Now it has been sitting in the exact same spot for 15 years and is buried up to the axle. My goal is to get it back on the road but before that I actually have to get it in the shop! I did manage to get it running in part one:    • Freeing Jimmy - 1961 GMC K1500 Sitting for...   Now will it actually move?
