Question Spedometer Question

I need some advice on my Speedometer.
Running OEM size tire front & back.

Earlier in the rebuild I sent the speedometer off to North Hollywood to be rebuilt...
(the gear had dissolved during 16 years of storage and the unit no longer worked)

I have chased wire and they appear to be good but... while driving it reads about ~30 MPH low.
30 @60, 35 @70

What else could it be?
Bad Sensor?

Inside the trans, on the pinion is a plate with 8 magnets. If one on the magnets drops off you loose 12.5% of your drive.
Standard replacement part and you can pull the pinion in the car. 915.318.045.03
