Speedo gear change
 

I bought a a speedo gear change from Steeda yesterday. I got on the phone with the guy and gave him all the info and he told me how many teeth the gear had and even what color. WELL! It gets here, I install it, and the speedo seems the same. Ever happen to you?

Cmon some1 has to know.

Did you try and change it from the stock? I know when I changed to my 3:55's, the shop called and supposedly got the right one for the new gears, but it was off too (21 tooth). So I called a guy that sold Ford upgrades, and he said I needed the black one (23 tooth I believe). It has been right now. I have 16" wheels.
It's been a while since then, but that's what I think I remember.
Hope this is what your asking?
