speedometer

Ive got a 72 f100 with a c-6 tranny. My question is, how do i recalibrate the speedo after a rearend change. Is it in the dash or the tranny. How would I go about this?
Thanks, Jaret

You change the gear on the end of the speedo cable at the tranny, if the proper one isn't available then the gear in the tranny can be changed.
