1972 Duster 340 garage find

I just picked up this 1972 340 duster. It has the matching numbers engine and trans fender tag and build sheet. All original sheet metal the motor is never been apart. Car was parked in a garage in 1985 until six years ago when the gentleman I bought it from bought it. All original interior that is in very good condition the car really is unmolested. I'm excited about the car let me know what you guys think and a ballpark value . Original color is the tor red, not a highly option car but I'm liking it! Thanks and happy new year !
