while i replaced my motor and sold my old one, the guy who bought my motor saw my k-member and said mine was different from his because mine had a bunch of factory cut holes compared to his solid k member. my car is crystal white with black leather interior, cobra labeled steering wheel, crab claw wing, and originally no decal on the decklid if anybody cares.
3.08 gears are a standard package for the 94 and 95 Cobras, but there was an optional package for 3.55 gears, aluminum gt40 heads, and etc.
They didn't roll off the assembly line with any options other than COLOR and Coupe or Vert.. That's it.. Period.
I'm not a big production numbers kind of guy, but you could get a Cobra-S with cloth seats. You could order the car with any gear option you want, even a 3.73:1. Never heard of getting them with aluminum heads though. My friend found a set of original Cobra floor mats on ebay recently. He was looking for like 7 years, and ended up paying $240 I think. Kurt
