The Ford Red speedo gear I just changed mine, you should be able to get it at your local speed shop for about 5 bucks

do you have the tremec 3550, and how close is it to the actual speed

I have a T-5 but a couple of my buddies have the Tremec 3550 and they are running the same speedo gear that I am and they are right on the money.
