Here's the repo stuff to make a Daytona/Superbird. These guys are the ones who make all the cool "phantom" 1-of-none wing cars that have gotten ink the last few years.

Don't forget that '70 Superbirds had '70 Dodge Coronet front fenders, so those will have to be swapped back on as well. Hard to imagine now that a 'Bird was so sale-proof by 1971 that it made sense to put a whole FRONT CLIP on, remove the wing, and paint most of the car to make it go away.
I think they're definitely worth more in wing trim. Would a ZL1 Camaro be worth more with the random small block put in after the dealer sold the engine to a racer to try and get the $7000 white elephant off his lot?.
I hope you'll show pics if you're successful! I think the Cars In Barns site might show a couple of Superbirds sans the pointy beaks, but with the telltale rear window treatment (the flush mounted rear window and resulting mandatory vinyl top would not have been changed back)
