SGTFURY62 OP top fuel Joined: Feb 2006 Posts: 1,954 Illinois	Anyone have a good lead on where to purchase a speedometer pinion gear? In my 63 plymouth I switched over to 3.91's and speedo is way off. I am running the original 63 auto trans and need to find the correct gear which I believe is an 8 by 20 toothed gear? Help.

I believe Year-One sells them too. They are "color-coded," There should be a link about them in the Moparts Tech archive, top of this webpage.

Cause pre's are rare, used or NOS only is what I've seen. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Funny thing, I never got one email on a NOS 2538932 (66 and later years) gear I have for sale here on Moparts for $25 and the dealer wants $79 for the same thing.

Here's the info from the 1965 parts book. 1963 info is the same. The factory never made a gear for the B bodies with 3.91:1 ratio. You had to use an adapter made by stewart warner to have a correct speedometer reading. 5467817-65speedogear.jpg (2856 downloads)

The early 904 and light duty standard transmissions have 7 teeth on the drive gear. As stated earlier, high numeric gear ratios most often need a reduction unit unless the tires are large in diameter. 5468074-Speedoends.jpg (1894 downloads)

I am only gonna guess that one of those stewart warner adapters are NOT easy to come by?
