I Dont Think U Will Have A Problem....i Dont Know For Sure Cause My Car Is A 92...i Went From An 85mph To A 160mph...it's Pretty Accurate...all I Did Was Swap Out Da Speedo...i'm Pretty Sure It Will Be Just A Straight Swap In Your Case As Well...again Im Not 100% On Dat. I Think The Only Time You Will Run Into The Speedo Not Reading Correctly Is If You Change Rear End Ratios....the Speed Sensor In The Tranny Is Geared For A Ratio Range.....like 3.73-4.10, When I Went From T-5 To Aod, I Had To Put The T-5 Speed Sensor In The Aod To Get The Speedo To Read Right Cause The Aod Originaly Had A 3.27 Rear End Attached To It.....i Think U Will Be Fine...but Fo Sho Ask Sumone Who Has A Later Model Stang

If you go from a 120 mph speedo to a 150 mph speedo it will read incorrectly. The MPH numbers will be moved to the left to squeeze in the extra 30+mph. The higher speedo you get, the higher it will be off.

1.) Fixes, get a tuner and tell it you have different rear end gears that will give you the proper ratio to set the speedo right.

Pros: Speedo reads correctly
Cons: You mileage on your odometer will not be correct because you are telling the computer you have different gears when you really don't.

2.) Take your car to a calibration place. I don't remember what they are called, but they can calibrate your speedo for the gauge you are using.

Pros: Speedo will read right, odometer will read right
Cons: No idea what the place that could do this would be called.

So, basically, those are your choices. Of course, you obviously also have the choice of leaving it as is and just knowing that when the speedo says you are going 70, you are really going 50...or whatever the shift ends up being.

Hay 01stang, Just Get A Speedo "whole Dash Cluster" From A V-8, Mileage May Be Incorect Like Smurf Said.....the Only Reason For It To Read Incorrectly Is If U Change The Gear Ratio In The Rear End....easy Fix, Change Speed Sensor In The Trans For One That Matches Your Gear Ratio...any Stang V-8 (close To Year Of Your Car) Speed Sensor Is Fine, As Long As You Dont Go Past 4:10....anything Past That And U Will Have To Call A Tranny Shop To Get The Right Sensor, Or Do Wut Smurf Said......they Way I Am Tell'n U Is The Cheapest. If U Change The Rear Gear U Can Get The Speed Sensor From A Junk Yard......easy Swap..it's Held On By One Bolt On Tranny Case....i Went From 85 To 160, It Also Helps When Your Best Friend Rebuilds Transmissions For Police Cars And Taxi Cabs,,, I Got A Badd Ass Aod!!!!

you can buy the GT gauge faces, white gauge faces if you want (look better than oem gt gauges) and just get your speedo calibrated (only 99+ can do this)

the v6 gauges look better and are easier to read anyway
