![]() I recently changed the rear in my 99 Cobra from the stock 3.27 to a 3.73 ratio. How do I recalibrate the speedometer. The mechanic said the speedo uses a magnetic pickup and not a toothed gear at the transmission. Reprogram the computer???

![]() Call Dallas Mustang and see if they have a Speedcal to fit your Cobra.
Be sure to say whether you're using a stick or AODE. www.dallasmustang.com ------------------ Adam "Hammer" Packett: Moderator, Gulf War Veteran ![]() ![]() |

![]() Thanks for the tip. The speed cal box is just the thing. Sorry you told me about Dallas Mustang, could cost me a lot of money. They got some nice toys!
