'70 - '72 are plain steel (so is the '67 - 69 A-Bodies), In '73 they added a Woodgrain "Bezel"/Plate to the door to match the Instrument Cluster and Radio/Climate Control Bezel/Plate.
They bolt up the same and interchange, but the pre-73 models lack the bezel.
This is a '73 Glovebox Door, Radio Bezel and Instrument Cluster (My dad's '73 340 Duster)
This is a '71 Glovebox Door (with Key Lock), and '67 Cuda "Rallye" Instrument Cluster (My '74 Duster)
Notice the '71 Door doesn't have the woodgrain bezel.
Yeah my 74 has the woodgrain, and I was looking to go to bare metal. I was just making sure the bolt uop the same. Is that an e body console in your dads car? I also keep seeing cd players in alot of cars, how did you support it inside the dash?
