After work today, I got a little time in the SpaceX shop to drill the other pushrod tube. I measured .250 inches from the end of the tube in multiple locations and wrapped tape around the tube to mark the circumference. Similar to last time, I held the tube in a piece and angle aluminum while I drilled the part.
Before installing the cap, I wrapped plastic tape around the part. This allowed a press fit between the tube and the cap to be achieved. All drilled holes came out fine.
