Keep it stock, or make it your own?

The only car that I have that will be put back to stock is my 70 340 Challenger. I've owned it since 79, and the only thing I ever replaced on it was the alternator and brake pads. It's numbers matching, and all the bolt on do dads are date code correct. Back in the day, it had L60-15's on 8" Cragars on the back, and E60-15's on Cragars up front. I may put new Cragars on it with big tires, but I have the 15 x 7 Rallyes already restored and in boxes. Every other car I have will be modified to suit me and my wife! I am a firm believer in doing it your way!
