Questions on 5.0 trim levels

I was wondering what the difference between the lx and the gt was. Where there any other trim levels? Also which one is best for performance mods? thank you

The GT and LX are almost identical except for the obvious exterior differences(sp?). I have heard the LX is a little quicker due to less interior weight (no power motors) and they have a little less in the ways of ground effects. I am not sure about the suspension, i think they are the same but that is just a guess. Someone else can clarify this better. Which is best for modding? Which ever you like best.

LX notchback has the stiffest chassis of all foxbodies..
