Engine/Transmission (1998.5 - 2002) D80/tire/Speedometer Question

[Alphacowboy]

So, i went in and had them recalibrate my speedo for my new tires. I gave the guy the exact number of RPM (revolutions per Mile) from BFG for my new tires, and he plugged that in with the DRB tool, but then it asked for the Tone ring tooth count, it said 102, so we left it... BUT, my speedo is still way off. Its about 5-8 MPH fast. Any ideas?

It must be the wrong ring count but I don't know what is correct for the Dana 80. Anyone else have an answer?
