Speedo gears TH700

Need a correct set of speedo gears for my TH700. I tried to use a calculator I found on the web, might have been TCI's calculator. Didn't work, cause now the speedo is even more off than it was.

I have a 10-bolt with 3.42 gears, and 245/50-R16 tires. What kind of gears do I need?

If anyone have got the correct gears and are willing to sell, please contact me. It is urgent.

Sidenote, I live in Norway, but I will pay extra for expedited shipping.

Thank you.
-Dennis
