Bah...I'm not in to speculating on parts and what not. I have it to enjoy NOW. My car itself will NEVER be put back to stock, so I'm not concerned in the least. Right now, the parts are worth whatever I can sell them for now, not later.Yes they are different. If I was you, I would keep them in a box and with the car! As the years go buy the original componets will only add to your cars value even if they are not on the car!
