I have a 1978 C10. Upon replacing all the universal joints today, I made it to the rear joint and it was the factory joint with the groove cut in it, filled with hard orange plastic. From my research, that’s from the factory. But I cannot find a replacement that’s the same. If anyone can help me with a part number or link, it would be much appreciated.

That plastic is injected and has something to do with initial assembly. When it comes to replacements, they should just be a 1310 u joint aftermarket will not have it.

^^^^ this

Once the glue is burned out of the factory ones just match the cap diameter and width of the joint and use the included clips to secure them.

It is a 1310 unless you've installed a beefier drive shaft that uses 1350s it'll be the one I listed
