“Parts for these 1st gen Dodges continue to get more difficult to find, thankfully there are companies dedicated to keeping these trucks on the road.

If you are changing your tire size or just missing your ratio adapter

Very quick response to my emails and lightning fast shipping.
Thanks Jim!"

After some discussion with the seller about the correct ratio,
it was assembled and sent quickly. Once installed, the speedometer reads correctly. Spot-on.

Thank you!
