Tachmeter cable retention bolt

The bolt is lose, its either broken off in there, or something. I cant find it on any parts diagrams. Can anyone help? I don't know what to call it. I need its dimensions so I can see whats going on.

I assume your asking about that same 1979 limited? It helps if you specify a model in each new thread.

I believe that's part 29 in the following schematic.

Thanks. It goes in the cover and keeps the tach end from coming out. I guess that's right but I didnt expect to find it there. I have to check valve clearance and I guess I will get a letter look then.

It actually screws into one of the cam journal caps, #3 in that schematic. That one cap sticks through a hole in the valve cover with a seal where it does. That's why you find it in the "Cylinder Head" section.

I cant tell whats going, doesn't look like the right bolt though. Do you know what size it is? I may just go to the HW store and pick up a few and see what works best. It basically keep the tach cable from backing out.

If you look at the website I linked it says part 29 is a 5x20 hex bolt.
