Recalibrating Speedometer

[93redzj]

Can just any shop recalibrate the speedometer or are there only certain shops? Just got my rearend swap done and both axles re-geared and now have no idea how fast im going. The jeep read 70mph(limit was 55) going up HWY49 today and I was still getting passed like I was doing 20mph.

Thanks
