You said that the 71 was a cuda. What happened to the original gilled fenders? Looks more like a BH23 71 Barracuda which is worth about half of what a BS23 70 Cuda would be worth. You might take that into consideration.
I've sold all of my 70 Cudas and Barracudas and kept my 71 Barracuda and my 71 Cuda. They're my favorites. When in doubt always stick with the real deal Cuda. They will always be worth much more.
