Need a stock speedo gear
I always thought that the SpeedCal worked in replacement of the speedo gear and not with the speedo gear. When I had my 3.73s put in the guy put in a different speedo to get me close. When I had the 4.56s and speedcal put in, I didn't think to mention that the speedo gear wasn't stock... now instead of 5 mph over like I was before.. I'm now 5mph under.
Anyone got a stock speedo gear on 'em?
