You might want to first ID the year of your engine.
It was most likely not standard equipment on a 1962 C10?

Then, buy a shop manual for that year.
The Links section has names of vendors.

Egge and Kanter should be able to supply parts.

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