Also if you are looking at a Superformance vs. a BDR keep in mind some the items standard on the SPF:
Limited slip diff
Heater/defroster
Chrome over brass windshield frame
Battery box integrated into trunk
No recycled parts
Oil cooler and hoses
Several others we can document if you wish further info
Some of the items we have such as the original style gages and seats may not fit with your build vision, but can be modified. It appears you are looking for a "hot rod" that visually apes a "Cobra" more than a traditional Cobra.
