Speedometer Driven Gear

I have a '66 F250, 435 NP, 4.10 gears. I need to know which driven gear I need (didn't have one when I bought the truck).
Anyone know or have a good guess?

There are a couple on ebay at item #8052595101
There is also a set of five on ebay at item #8051485850

The two are going for $16.00 and the five are going for $42.00 the run $10.00 at Ford the last time I bought one for my truck.

I dropped mine to a 15 tooth from 18 when I dropped my gears to 3.00 from 3.50.

Good luck..

Do a google there is plenty of calculators on the web.

Don't forget tire size, that comes into play determining which gear to use.
