I just finished this section last week.
See this thread:
I couldn't get the rod ends in the tube even before primer.
I ended up getting a wheel for my Dremel tool and sanding the inside of the tube until they fit snugly.
I chose that over sanding down the rod end itself.
Then I primed the inside of the tube, let dry, and riveted it together.
The powder coating of mine barely wrapped around the insides of the tube. You definitely want to prime, as you won't be able to inspect this at all later.

I also noticed that it says to prime this part when done... my pushrod is powder coated white - is it really necessary to prime?
