What Gears are You Running?

[copper]

I have a 3.73 in the WI SSP and the speedometer was way off when I drove it. I checked the gear at the end of the speedometer cable and it was a 21 tooth but some of the teeth were worn off which could count for the needle wondering. What did you guys do to get the speedometer close to accurate? I read that the trans drive gear in the 93s had 8 teeth and on the chart, it indicated I would need the max of 23 tooth gear on speedometer and it would still be a bit off. They also mentioned the nylon gears last a little while and then it may break some teeth like the one I have. The other choice was to change the trans drive gear to a 6 or 7 but it is a big job. Any help would be appreciated or will I have to just live with it. Thanks
