Speedometer Calibration

[H8TOW8]

So, I am ready to put on a new 3.45 rear differential on my 2000 RT/10. So, I guess I need to pick up a speedometer calibration unit. I have heard Accu-Gear is good ... any advice? I have the gears already ... just need the calibrator. Best option?

I got Unitrax gears and they came with a cal box already set for the 3.55

Well, I have the gears but they did not come with any box. Advice on best way to go?

Gadgetmann,

Do not mean to hijack your thread, but why 3.45s instead of 3.55s? Are you planning more upgrades in the near future?
