Speedo Gear

[DJCUDA]

Hi All, I would like some assistance on speedo gears, I was finally able to source parts for my
8 3/4 diff and am about to replace the 2.76 ratio for a 3.23 ratio, I was told this will now affect the speedo reading. Can anyone advise me what teeth numbers are required for the speedo gear to suit a 3.23 ratio, I know Classic Industries have a number of gears to choose from.

Cheers.
