I recently installed a 4:10 gear in my 69 Nova and of course the speedo is off by a bunch. I have a turbo 350 trans. Does anyone know where I can purchase the correct speedo gear and which one do I need ? Any help would be appreciated. Thank you.

I get my speedo parts from a transmission rebuild shop, or supplier

Speedo gears

All speedo gear colors are available on EBAY or Ground Up--SS396 .com.

I was off by 10 mph and went with a ratio adapter. Speedo is correct now.


Speedo Correction Adaptor
Speedometer not giving the correct speed? Don't drop the pan or struggle with locating increasingly scarce internal speedometer gears.
California Performance Transmission has the answer. Simply screw our inline adapter into the transmissions speedo drive and your speedometer cable to the back of the adapter.
Here's how it works; Use a GPS device or your cell phone, when it registers at 50 MPH read the speed indicated by your car's speedometer and send it to us. We'll calculate the correction ratio, gear the adapter correctly and send it your way.
