I have an 03 Cobra that was just recently purchased with the light grey/silver interior. The rear seatbelt that is under the rear seat is no longer in the car. This is the female section that has the push button to unlatch the over-shoulder belt.

I do not require the over the shoulder belts. I have these installed in the car.

If you built a race car of the 03/04 vintage and removed your lower rear seatbelt sections, I would be interested.
