1968 318 Cuda, restore or clone a 383 Formula S?

Thanks for all the responses. If the car is not really worth any more being a numbers matching 318, I like the idea of a 383 with air conditioning. I could then add the 383-S badges and paint it like the one my dad had. Now if I can only find the time to work on it.

Are there any good places to look for parts, besides Ebay?
