The stock drive pins are the same diameter as the hole in the top-shaft. You may need some Loctite/JB Weld -or- a larger pin if the hole was widened when you put the drill bit in there.
the diameter of the hole is roughly .001 bigger now. so i guess ill use some loctite, prollu loctite it to the shaft and then to the gear also. that should hold up.
thanks for answering my questions, now i just gotta find what i did with that pack of drive pins!

They are sneaky little things... Especially around motors with strong magnets! I put a bag of them in the same drawer as a motor once and the next day I pick up the bag and it's empty!?... A week later I needed the motor and, wouldn't you know, they were all stuck to the side of it?!!!
