I looked up the mach 1 and it comes with 3.55 gears and the new 05 mustang's will be getting these gears as well i believe. What gears does the 99 + gt's come with and can you put the 3.55 gears in the gt's?
What performance mods does the new mach 1 come with that the gt's don't other than the shaker hood?
