I'm changing out my differential from 3.08 to 3.73 gears. Will I need to make adjustments to my speedometer? If so, how?

You'll need to change the gear in the trans. Where the speedo gear attaches to the trans, there is a small clamp with 1 bolt, take it off and the "bullit" will pull out, with the gear.

There is a gear in the transmission that will need to be changed to the correct gear for the rear ratio. I am familiar with the muncie 4 speeds and it is a plastic gear inside where the speedometer cable attaches to the transmission.
