Over forty people viewed your post but no one answered you previously because we have no idea what you are talking about.
James/hotshot is trying to be helpful, because the only late model Mustangs with horizontal tail lights (instead of verticle tail lights) were the 1994 and 1995 Mustangs. There was no Shelby model in either of those model years. The nearest thing to a Shelby was the SVT Cobra. The rarest of these in those years are the 1994 Indy Pace Car replica convertibles (only 1000 built, all rio red with tan interior and tan top - see pics below), the 1995 Cobra convertibles (only 1003 built including 499 with the optional removable hard top, all black with saddle tan interior - see pic below), and the 1995 Cobra R (only 250 built, all in white with the tan cloth interior that was shared with the V6 Mustang - see pic below).
