Also be aware that there are right and left helix on the gears.  Depends on whether the original application had the speedo cable aimed above or below the outplut shaft.  My grandson pointed out to me the other day that his NPD Mustang catalog lists gears by right or left and number of teeth.

If you have the original gear they may be able to determine the teeth on the other gear that is inside the tailshaft. They have to match in numbers or the gear will just tear up. I don't know how many different ratios there are but I'm sure someone here does. Chuck in NH

Somewhere I read several years ago, that each tooth on the cable end of the gear is supposed to be 5mph?? I think thats the way it was. I know it wasn't the driven gear in the trans. itself.

"compatible... we don't need no stinkin' compatible...!"

thanks for the input; guess I'll take mine to the NAPA store with the oldest-looking counter help and see what happens!

thanks,Mark

The Ford speedo gears for the transmission end of the cable are of the same basic design from 1957 thru the mid Nineties.  You just need to know the number of teeth needed and if that particular number of teeth is compatible with the spiral gear on the transmission tail shaft.

Evidently dealers in different areas carry different parts. I bought a couple from concours, and then was told by a buddy at the local NAPA store that he could get them also. I'll have to ask him again and see if I can find the manufacturer. Forget Advance and Autozone,"what year is your car sir?"

Aren't the speedo gears the same from 57 on up into the 70's? I think mine is a mustang piece? For some reason I couldn't get a definitive answer to the same question. Ended up taking my old gear to the parts store. (I use a 57 up cable with my AOD) Chuck in NH

I've never heard of NAPA even having these, I'll sure give it a try.
