Q: Speedometer Off
This wonderful hunk of junk from said he had a gto rear end put in, and this is what causes a 10 MPH speedometer offset (due to different gear sizing for the speedo linkup) is there a way to correct this problem easily (if indeed this is the case)?
A: The reason your speedometer is off by 10 MPH is that when the rear end was swapped out, a new one with a different gear ratio was put in it’s place. The gears that drive the speedometer are loacted in the transmission. To correct this problem, you just need to install the speedometer gear for the differential ratio you currently have in your car. Claasic Industries sells these gears and they are easy to replace. Just tell them the type of trans you have and the gear ration in the rear end.
