Speedometer reads too high
I recently installed a 3.73 posi rear-end in my 1991 Camaro RS, and now my speedometer reads about 10mph to high. Any ideas as to how I can fix this?

Actually his car being a 91 should be an electric speedometer. Atleast my 91 was factory. The computer would have to be reprogrammed for the calibration.

I replaced the drive and driven gear, which was a mistake in hind sight. I had to beat the drive gear off, and broke the replacement, requiring an other one. The dealership told me I need the combination. Just replace the driven gear with the correct one.
