I opened the valve cover and removed the rocker assembly on my 1960 C10. There is a lot of wear on the shafts and the oil pipe part in the middle is broken. I would like to replace the oil piece (is there an official name for this?) so I can see if the engine will turn over and run. I suppose I can replace the other parts or even the whole assembly if that makes sense but is it even possible to source individual parts for this?
Pics below show the part I need and some of the bad wear on the shaft.
