1939 (VC) 1.5 ton truck.. Trunnion Bearing Lock Ring

[Philippe Jeanneau]

I am in search of the u joint lock rings for GM 609948 U joint repair kit...The original GM number for the circlip is GM 365316. I also have the following dimensions if helpful:

1- Cap outside diameter: 0.971"
2- Can Inside groove: 0.876"

3- ORIGINAL STYLE Lock ring (Round) outside diameter: 0.979-1.025
4- ORIGINAL STYLE Lock ring (Round) inside diameter: 0.826-0.857


5- OTHER REPLACEMENT Lock ring (square) outside diameter: 0.985-1.030
6- OTHER REPLACEMENT Lock ring (square) inside diameter: 0.81-0.86

Another dimension I have is the thickness of original being 0.085" and a range in thicknesses of the square samples from 0.055 to 0.058... I have found a newer GM part, 26056600 and Spicer number 10-7-29, but I am not sure if they can use it for my application. Your help is appreciated here, thank you.
