well if its a 99 up manual buy a dallas speedcal from dallasmustangs.com i have had one for over a year maybe nearly 2 and its been great, it is said to work on autos but not sure so ask them first. if not you will need a chip. for pre 99 you can only pop in a 23 tooth speedo gear and it still wont be right, if its a manual you can pop off the tial shaft and put a diff drive gear to match with teh speedo gear you choose and get a correct reading but not sure which gears you want to get.

:mad: thanks but i already bought one...i think it was the red one...i gotta pick it up on wed.... i talked to gefracing and the guy told me that this gear would be the best one...(C40Z17271A).

and how would i fix that 7mph difference? that's still alot! i can't take my car to the dealership to have it recalibrated cause the speedo is gear driven.

is it an auto or manual? not sure if it works for autos.... or pre 96s at least. its not hard to hook up pretty quick actually but i would not use the connector they offer for the all time power it kept comming lose on my car just use a sodering iron or something better than the little snap no connector they provide.
