You own and love an original 69 383s, what’s next?

The car is yours, make it as you wish. If this were 1970, nobody would care what you did to “your car”.

However, I suggest removing and preserving any parts that you decide to upgrade and replace so that they might be reinstalled later. After all, they didn’t make many of these and it isn’t 1970 anymore. Making it what you want it to be doesn’t mean chucking the past entirely...
