I have the bump stripes on my laser red 95 GT. It was an option that some have and some don't. Also, if you look closely at some of the side ground effects on these GT's, they are also slightly different behind the front wheelwells. There's a whole lot of small differences that people don't notice, I actually had to park my car next to a buddy's 95 GT and check out each of them. Leather was an option, I too have black and dark grey cloth seats in my stang. I'll post a pic of my car here, and look to see if you can see the difference at the front wheel wells for the ground effects. Mine rise up a little higher than 1Hot5.0's do just at the front of the side ground effects
