62-65 early model speedometer gear Chart?

Never seen a calculator that works for Early A's. If it has a 41 tooth, definitely not for our cars.

If you don't have a technical service manual for your year you should really have one. That's probably what's missing.

Thanks for the pictures... looks like maybe a 19 or 21 tooth . Just what I needed

Yes, have the TSM. NEVER far away :thumbsup:
But 64 only goes to show 3.31 or 3.55 axle ratio so trying to cipher an appropriate change to match things up with the 3.91 I have now.
