I have all of the original parts from my car that I have upgraded or replaced. My car is a 2 owner 1 family (bought from father) car.The question is; Is it better to keep my orignal parts for value to the car or would it not really matter anymore? The parts are the orignal carb,intake,heads,cam,rear center section, axels,radio and some other misc. parts. Are these parts needed to keep it or have it mean numbers matching?
