What's the difference in width? I don't want to go narrower. Cat back exhaust would be included in the trade. As far as I know, I still have the stock gears, which I believe are 3.27s (I'm the 3rd owner of the car, I'm confident that the guy I bought if off of didn't do gears, but I'm not sure about the original owner).

Any '99 - '04 owners out there looking to swap? GT's or Mach's only please!
