Out of the 3 - 1)strap-2)console-3)seat coverings, I only pointed out the 3)seat coverings as a definite departure from original and correct. I cannot comment on the other 2. I said that they, the strap and console, are options and possible, plausible, correct to this car.
As to the “clone”. Once your car, do as you please. It is YOUR car. If you want to make it into a clone, irrespective of which “will be worth more”, that is just your taste and ideas. The car is basically a “rolling canvas”, that the owner / artist uses to express their own ideas. It is far too premature to make that assessment to determine if the car best be left alone or modified based on a few pictures. Some guys will make the “clone” of their dreams, yet be mindful and appreciative of originality and keep the original pieces boxed up and not separate them from the car. You have many options. As far as value? Some will think the value is enhanced with that modification. Others won’t. So you will just have another segment interested, and value is not hurt. There is always someone seeking out a specific type (original,restored,hot rod, day 2, restomod). The list goes on. So you won’t be hurt no matter which way you go.
