Bloo Posted March 2 Share Posted March 2 Chevrolet speedo gears weren't interchangeable for different gear ratios in that period, and were sold as a set (worm and pinion). Don't neglect to change both, unless you are dead sure the worm you have on the u-joint matches the pinion you are putting in. I second the recommendation for the VCCA forums and the Stovebolt forums. Good luck. Link to comment Share on other sites More sharing options...
oldsteel Posted March 3 Share Posted March 3 Do you have the original one. I have a speedometer drive gear unit but the PT number that was on the lid has been lost along the way here is a picture of what I have. Link to comment Share on other sites More sharing options...

Flathead48 Posted March 6 Author Share Posted March 6 Old steel, his mechanic said there was a difference, not sure if he said number of teeth or length. Thank you for all your effort in helping us. Regards, Rick 1 Link to comment Share on other sites More sharing options...
