Hey I finally ordered my new speedo gear, a 33 tooth yellow one and I also ordered the gaskets (o-ring and small rubber ring). The o ring is way too big and I'm not sure how the other small rubber piece goes on.

Also I'm in minnesota so Im not going to be drive it around in the snow to test it. Can I just keep the rear end jacked up and run the car to see if the speedo needle moves. I don't have a posi. Can it run if all the fluid is in the front of the tranny?

 

Here is a picture of my old 27 tooth gear with my new gaskets.

 

Do I need the small rubber gasket and how do I put it on?

 

the o ring seals the gear housing to the tranny case
