I have lost the plastic gear that attaches to the speedometer cable, I have tried mirrors , my little finger inside the housing doesn't locate it, it has to be inside the extension housing some where but I can't find it. The guy I bought the car from came over yesterday and thought it would be a snap, he couldn't find it either.

I even put a new bag on my shop vac and put over the opening hoping that woukd bring it forward but no luck.

My question is, can the plastic gear get into the out put shaft and cause a problem if I drive the car and if not I will order another speedometer gear and  go on about my business.

Looking at the extension housing cut out there is plenty of room for the gear to be where you couldn't see it.

Appreciate your help.
