So, let's talk speedometer, after updating rear end gears

[Bull1tt]

Went from 2:94 to 3:73 ratio rear end gears, I think it has an 18 tooth gear in the 727 trans. What's my solution? Orig gears are about impossible to find for 62-5 trans. Imperial services never returned a call or e-mail, they used to sell the adapters.

Try calling these guys. I have not dealt with them but they say they can make speedo gears on their web page.

They don't have the one I need (ratio adapter) in stock.... have to call back in a week. They show $62 for the adapter on website, place in Texas will build one for me now, but is $115.
Somebody else must have them, any ideas? The trans has a 16 tooth gear.
