Speedo Fix, Dana 20-HELP

Alright, i got a speeding ticket and need to get my speedometer fixed. Some place is saying 140 bucks because they have to build an adapter to go on my transfercase. Now i thought i was pretty sure it didnt take an adapter and i have heard the part is only 15-20 bucks. Could someone tell me if all i need is a new gear itself and where is the best place to get it from. And how do i know exactly what gear to get. And will this new gear fix the speedo exactly? Thanks
Andrew

once you figure out what you need call the dealer or you can give Dan or Gene a call at Turner 4wd.

I read about advance adapters offering a beefier output shaft for the dana 20. One of the benefits was being able to easily regear the speedo drive. That leads me to believe that there isn't an easy way to fix the dana 20 speedo error.

Save your money..find a cop and tell him you want him to check your speedo...drive by him at 50 and whatever he clocks you at save it in your brain housing group as gospel. The mph difference will stay the same regardless of your speed so you will know where your rig is at...according to "THE LAW"[img]images/icons/tongue.gif[/img]

WILL, I read the same thing in this month's Four Wheeler. I'd call AA and find out, they'd be the ones that know.

The big tires increased the vehicle speed at a given RPM. The short gears reduced vehicle speed at a given RPM. They've about cancelled each other.
