speedo gear

hey all,
ive gone to 4.88 gears from 4.10 and my speedo is off by about 4-5-mph at 60mph. according to a chart online( with 33" tires) i need a speedo gear with 41 teeth, but they are nowhere to be found! at least im going slower than the speedo reads, so ive got a little play, but id still like to know how fast im going. any help would be appreciated

So the gear for the speedo is in the tail of the transfer case on a TJ? I looked at the sites, but how do you know which gear to get? I have 33" tires and my speedo reads slower than I'm actually going. Is this correct?
My mileage dial also states that I've gone shorter distances than I've actually gone. My stock Ford will state 30.3 miles and my Jeep will state 24.8 on the exact same route.

Here is the chart and you will need from a 30 with 3.55 up to 41 with 4.88 R&P
