as soon as my dad gets his new setup, his 355/th350 is going into my station wagon. i would like to keep the speedo accurate, but my question is, can i swap the speedo gears from the 250 trans coming out to the 350 going in???

The Driven gears are the same. There are a few different sizes/types of Drive gears. You'll just have to check. May only need to use the same retaining Clip & Gear, Trans to Trans.

What rear gear are you using? What is the tire size?

I believe its 2.29, and the tire is a 245/50/16

If the Gears are correct for your app. use both, Drive & Driven.
