I'm trying to determine the proper speedometer pinion gear for my 300G. My speedo reads lower than it should and I'd like to see if I can improve its accuracy, at 40 mph I'm actually doing about 45. I'm running 235/75R15 tires and a 2.93 rear axle. Any suggestions on the proper gear? I know they come in different colors to differentiate different ratios.
Thanks!
