You can not get repro front side marker lights for a 70 from NPD. Check out their catalog and compare with the price of this "NOS" marker light you are looking at. The front is tall and now very wide, like a curved rectangle. The 69 front marker lights are the ones that fit in the valance and look like a sideways rectangle. If the Dude claims his lights are NOS, tell him you want to buy the lights together with the FORD boxes they came in. Otherwise, they could be repro stuff he is pawning off.
good luck. Yeah, they are orange in front red in back.
