What speedo gear do I need?

[FoxRod87]

I have a 96 GT with a t-45 trans and want to go with 3.90 or a 4.10 gears. I just want to know what speedo gear do I need to get to make my speedo correct? Or can I just buy a SCT Tuner and change with it? I was thinking about buying one anyway. Thanks.

You cant correct it with the tuner, and I believe you want the white one with the 4.10 gears...not 100 % sure though. Also be aware, your speedo will still not be perfectly correct and you might as well buy a speed-cal from Dallas Mustang to get it to be more exact. ($100)

www.latemodelrestoration.com sells speedo gears. I dont know if they apply to your gears but you can give it a shot.

I heard 3.73's take the purple gear and thats the right one.

Your better off getting the speedcal. They are 100% correct.

If I get the speed cal I wont need to change the speedo gear in the transmission Will I? Just tell the people at dallas mustang what my setup is.

Correct. You wont need to change the speedo gear.

MY 96 Cobra T45 with 4.10's takes a white 23 tooth. I have to replace them every two years (5-7K) year because they get chewed up due to thin teeth.
