91 camaro rs T5 Speedometer wrong

Need help fixing off speedometer. Couldn't find a cable, (assuming it's electric?) But I upgraded to 3.73 gears and need help on how to set the speedometer to the proper speeds. Stock tires and wheels, T5 trans.

Any help appreciated!

Well what you need to do fortunately isnt too bad all you need to do is replace the speedometer drive gear to match your new rear gears.

You need to replace the drive and/or driven gears depending on what the previous gears were: 3.08 down you'll need to replace both, 3.23 up the driven gear.
