Hello All
I need help locating a speedometer cable gear, I have a 66 with a NP435 trans with a 4:10 posi. When I bought the truck the gear was missing and I talked to some people to find a new one but they all ask what color is the gear and how many teeth are on it. Unfortunately I cant answer that question, so im stuck in the mud on this one.

By the way I took of the cap that holds the cable, and I took off the L shaped unit from the trans that connects the cable to the trans.

Much appreciation for any help
