speedometer ratio adapter

I changed the gears in my truck I went from 3.07 to 4.10 and need to change the speedo ratio adapter. I need to figure out which one I will need. The one in the truck now has 1.2020 on it.

Re: speedometer ratio adapter

I just saw this thread on adapter calibration. I was wondering what was the fix for this. Is there different gears you can buy for the adapter? I changed my gears to 4.10 and tires are 33s in my 71 k5. Maybe a link or conversion chart somewhere?
