Road Runner Nest

I have a 73 Roadrunner and have been given information on where to find a 74 Roadrunner , Are the fenders and doors on both cars the same or did they change them ? I am not forsure what years will swap with each other . Any info on this will help .
Thanks ,

Regarding sheet metal. The '73 & '74 are the same. The hood is different (vents holes vs no vent holes) but is interchangeable between those two years.
