My Dart Dilemma

O.K. the plan was to sell my 66 charger, find a good A-Body preferably a 67-69 notch Barracuda with a slant and change a few things to my liking and use it as a daily driver. What I came across was a 67 Dart GT with 20,000 original miles. Thinking I couldn't find a better starting point than this I jumped on it. Problem is now I'm starting to feel apprehensive about using a survivor like this as my starting point. I was planning on the usual large bolt pattern change over with 8 3/4 rear and disks off a 73 up front, adding a/c etc. Not much harm so far but then I start looking at the body wishing I could loose some of the trim like I did my charger and with that I'm taking the car to a place where it couldn't be easily returned to original. I know it's my car I can do as I please but I'm starting to feel guilty about what I'm contemplating. So the question is... change it, or sell it to someone who'll appreciate it for what it is now.. a super clean 20,000 mile original????

Want to trade for a 1967 Barracuda fastback that needs drive train but has a pretty nice body? It is a V8 automatic car.
