Universal III Gripper issue/missing screw or pin?

Hello! I recently moved into a new studio and have been having problems with sticky grippers, which isn’t new to me so I didn’t think it had anything to do with the move. Today as I was printing, the pedal really didn’t do anything to raise the grippers so upon investigating, I went on the other side of the press and noticed this screw holding this piece on my finger to connect to the other piece (that pushes back and forth when I press the pedal) is gone! I’m assuming it happened during the move. Hard to explain but I looked in the manual to see what part it is and the drawing doesn’t list it. It lists “shoulder screw X-2276” as the closest part number but what I need is the screw that holds a little rotating ball into that shoulder screw. I just need to know what type of screw or pin I need – hopefully it’s something I can get at the local hardware store! Thank you!

That component is for the power grippers. If you open the door to the motor bay you’ll see the rest of the assembly (solenoid).
The pedal can still be used to raise the grippers without this eyelet attached. I suspect that either the gripper spring (X-7522) is broken or one or both of the collars (NR-310) is loose. See page 23 of my book. Image attached.

I don’t know what the spec for this screw is. Measure the diameter of hole. (My guess is 1/4-28 x 1″.)
