I have a couple speedogears which do not have the same number of teeth. I'm currently using one which has 12 teeth. I have one in storage that has 11.

I've been able to remove my gear by putting the tranny in neutral and while removing the speedo gear the big gear inside turns. Otherwise what about opening up the bell housing so you can turn the driveline (assuming yours in enclosed) while unthreading the speedogear. This way you can confirm the number of teeth you have.
