Dan, Thanks for the research. Interesting. I guess the ‘37 truck was just a step closer to a tractor than the passenger car and could have a little grease exposed here and there. Lol I always was under the impression from my service manual that in that year, the car and light truck shared the same basic rear just a different driveshaft length. I may try to fabricate something as long as it doesn’t restrict bolting the pieces solid together. It doesn’t move far. Anyone with suggestions?

If you are missing one component, you'll need an abundance of the others two.
