Re: What speedo Drive Gear for a 4.11 Diff?
Type 9 and E do interchange, I did this on my box but also found the speedo was still out so I reset the needle to about -10kmh !
If you change the worm gear to 6ti believe that will slow the drive gear down at the given speed .. It's one of those try and see things. Failing all that, take the speedo to Auto Instruments they can adjust bob weights / magnets etc to read accurater
