Have you ever torn apart an all-original car to build what you wanted?

My original Mopar was a 1970 super bee. Purchased off the military credit union lot for 650 bucks in 1977. All original never disassembled car, w/383, 18 spline, pistol grip, 3:91 sure grip. Pre-internet days, I was 18.
I beat that car all the way to the wrecking yard after discarding the 383 for a 440. I don't even have any pictures of it, lol. Fire engine red with dual hood scoops, was a gorgeous car.
