Look at a RC car supplier (like, Tower Hobbies) for "body pins" used to

IIRC, we used to use dental floss tied onto the pin and pushrod so you
didn't lose the pin.

Google "R clips" ( guess why they are called that...!) Totally agree
about a
light safety thread to avoid losing the clip into the bottom of the
