My '70 is a big disassembled project and likely will be for a couple more years while I have to put time into bigger priorities. The original frame was heavily modified by me in my younger years and the original Willock joint had an 18" crack through one of it's welds. I removed the joint to preserve it as-is and currently have the truck on a stock highboy frame to keep it mobile. The Willock swivel joint is two crossmembers made from 1/4" plate with tubes welded in and machined to accept bronze bushings. The shaft is 4" 4140 with a 2" hole bored through the center for the brake lines, park brake and electrical to pass through. The shaft is threaded with split locking collars on each end for adjustment. The crossmembers are plumbed for external zerk fittings. My joint was sloppy because one long zerk broke off deep inside and I couldn't get it out (broke before I got the truck). One side of the joint never got grease for the time I drove it.
The only, singular aspect of the swivel joint I did not like is that it lacks any provision to lock it out. You honestly do not notice the joint in the truck's handling on the road whatsoever, but you sure as hell do notice the joint when you put hundreds of hours into body and paint and the bed doesn't line up with the cab when you park in a parking lot 50% of the time. I also didn't like that the joint required an extra inch between the cab and bed so the bed could rotate without hitting the cab. I designed a replacement joint with a crivic coupling type locking mechanism and lubrication system so the swivel won't wear out like the original. It will also extend 1" when it's allowed to swivel so the bed won't hit the cab, yet it will look stock when I'm not using it. Of coarse I have to actually machine the new swivel joint and assemble the rest of the truck. In a couple years the pieces will start finally coming together.
Here's a video a civilian powerwagon with a Willock joint.
I have been told by several people over the years that there were 3 of these 1970 300 six F-250 4x4's modified by Willock for Pacific Power in 1969. I have never heard mention of what happened to the other two, sure would love to find that out.
