73 road runner fender tag

hey guys i know this isnt a question about an a body but im hoping someone can help me out. im thinkn of buying a 73 road runner but it doesnt have its fender tag..now is there any other way to find out if this is a true road runner? im thinking its a satellite but the owner is certain its a real road runner. but with a full vinyl top and a wood trim steering wheel is leading me to believe its a satellite. now ive never seen a road runner with a full vinyl top just the half vinyl top.
the owner is also saying a has a matching 340, 727, 8 3/4 rear and has a floor shifter. the vin number is stating its a road runner with the h code for the 340. but im sure you can transplant parts from road runner to satellite to make a clone. what would you guys do?
