Speed calibrator to fix Speedo?

[rcmonster]

I just installed 4.10 into my 95 GT Conv. It had 2.73's in it factory. The largest speedo gear I can Find is 23tooth and correct for 3.55's. Has anyone used the speed calibrator before? Does it correct the speedo the way it should?

I think Stanger007 used one and if it was him then he told me it worked great.


I might be thinking of someone else though.

His is also.

And when I do a gear swap, I plan on getting a speedcal.

I got the Dallas Speedcal too. Easy install. I too went from 2.73's to 4.10's. I checked mine at a speed trap and they are dead on.
