auxilary shaft removal

ok, i pulled out the rod where the rotor plugs onto. (auxilary shaft correct?) This is the rod that the distributor cap screws onto(the one i pulled out). My problem is the rotor doesn't spin when i turn over my engine. The timing belt and all other belts on front of engine are new(or were new few months ago when it broke).

There is a gear on this rod towards the bottom. I'm assuming it spins the rotor, however my gear is kind of loose. It's loose enough to spin with a little force from my hands if i hold onto the top where the rotor slides in. It will spin without spinning the rod. It also slides up and down a little bit. 1/8 of an inch. I can see a pin hole through the gear and rod if it's lined up correctly, not sure if that counts for anything though.
Is this supposed to happen?
So do i need to get this part new in order to have the car in working conditions again. (ROLL BACK, car died on highway, couldn't find problem, after 2 days of work looking for loss of spark we took off the distributor cap and noticed the rotor wasn't spinning but the engine cranks over just fine.)

cha ching

the rod i pulled out has a gear on it. i pulled the whole distributor i beleive and the gear is called distributor gear.
there is a little whole through the gear and rod for a pin,,, my pin is broken.
i wish to acquire a new one then problem (should be) solved.

Where can i get this, im about to call autozone but i think this is discontinued... wish me luck

btw got a spare pin anyone(if i can't find one i'll jam a nail in it and break off the ends) Me special ed but whatever makes the rusty son a gun run
