1949 Chevy Truck 3100 4 Speed Transmission

Okay, I have done all the testing and figuring and it is pretty much a given that I have a speedo gear problem. I can see wear marks on the teeth. It will catch occasionally but only for 10 seconds at a time. I found replacements on "Tim Tygart's Obsolete Chevy Parts Co." So how do I go about changing out the speedometer drive gear and the gear inside the transmission that turns it? I have never done anything like this before.
