Installing extrovert drivers

[Boondockin800]

I got a hold of a driveshaft with some 10 tooth (2.52 pitch) wahl bros drivers installed. Aftering holding it up to my track I'm pretty sure that one of the drivers is off enough to make the external teeth rub on the track windows. Does anyone have the measurements for the driver placement on the shaft laying around?

Thanks!

Are the teeth ctrd. on the wheel with the std. outside teeth on one side? I will measure ctr. line of the extro's anyway, And see how they stack up?

Yup. Here's a pic.

Here try these #'s Track outer dim. between track rubber edge to rubber edge = 9.90" Driver outer edge of extro is 5.00" from end of hex radius on 1.00" shaft from splined end to outer edge of extro. Outer edge to outer edge of extro is 9.30" Extro width is .640" If I recall Avid websight says to run the extro close to the edge of the track edge to keep track aligned in tunnel? Maybe someone set these up for least amount of resistance when running? Thats why there is .600 of wander of the front of track? But I think the track clips won't let it wander that far? Others on here may have a better understanding of where to run them, This is the way someone else set them up, Maybe for max speed?

Hope this helps
