Hello, Sven,

I am away from home for a few days, and I am away from my documentation.
If you get no replies here by Monday, I'll post photos and information on Monday

USA Chevrolet did not have a 1/2 ton longbed until around late 1955 or 1956. I do not know if the 3/4 ton Chevrolet parts were the same parts as used on your GMC.

You might want to join the oldGMCtrucks duscussion board. There are members there who have replaced those parts (and, who know sources for those parts). I'll contact one of them in Monday.

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
