Grm, the '72-'74's could come with a stripe, which is commonly known as "strobe stripes". They fit on the lower front fender and proceed about halfway through the lower portion of the door. But if you were to use these stripes, the car would need to have the Rallye package to make it a correct color and stripe combination. Otherwise, I believe the '72-'74's were available with a narrow stripe that follows along the body line..If it isn't a stripe, then I know for sure there was a moulding piece that ran the length of the body line and could come in several different colors. Hopefully this gave you an idea as to what stripe kit you could go with if you were to purchase the '73 Chally. Good luck either way!
