Speedometer

The other day when I took my truck on it's first maiden voyage, it felt like I was doing 80 when the speedometer said 70. I took the GPS with me yesterday on my trip to Helena. When I got to 63 mph, I glance over and the GPS says 70. Upon further inspection, my truck has 3.73's instead of 4.10's like I thought.

So, what do I need to do change the speedo gears in my 205 transfer case? Do I have to change the gear on the shaft along with the driven gear? Do they make a speedometer adapter?
