Strange speedo drive gear
Below are two speedo drive gears and cases that have 18 stamped on them. I cannot find anything about them in the Restoration Guidelines. Anyone got any ideas?

These were for one of the early V-8 cars and can be used on a Model A if one has a 3.54 ratio rear end.

The model A didn't have as many choices but there were a few for it depending on rear axle ratio. 19 and 21 were the only two on that chart. The 18 tooth is a good one for lower numerical ratios like the 3.55:1 but I'm not sure if they will work on the model A torque tube. Last edited by rotorwrench; 06-02-2020 at 12:12 PM. |
