I recently bought my first fox body its a 1990 gt i bought it for a project but i got some fender off a 91 lx and after trying to install them the fenders wont line up with the header panel so my ? Is will the fenders off the 91 fit my 90?

 

79-90 fenders are the same. 91-93 fenders are diffrent. Hope this helps

 

The only difference between the two is the wheel well opening. They are a little larger on the 91-93 models, other than that they should line up.
