gears

[98mustang2007]

hi everyone, I bought my 98 v6 about 6 months ago . It already had dual ex. tinted windows and cai. Iam about the 4th owner.Is there a way to tell if it still has stock gears.It is an auto and 1st gear gets to4000rpm really fast but 2nd is not nearly as responsive. I want to change from stock gears, also I have acess to about 4 diffrent gt complete rear ends from 1983 to 1990 will these swap out if not what year gt will swap and how difficult is the swap thanks

I believe the fox body rear ends are going to be too narrow for your setup. You will want to go with a 94-98 rear end instead.

As far as figuring out what gears you have now...who knows. If they've been replaced really the only way to tell would be pull the cover off and count the teeth.

I think the 94-98's are fine with the fox body rear ends but not 100% sure. I know the 99 up are 1.5 inches overall wider.
