New Mexican hookups?

Our '70 has headrests. Does the '73? I have a set out of a '69 w/o headrests that have been recovered

I know where several Duster shells in various condition '70-74 are that the guy want's gone. I also have a straight '74 Dart Sport body available here in Gallup. The rear deck lid was pried open and lock destroyed, but is a complete roller accept for tail lights missing. Slant six car that looks like the block was rebuilt. Top end gone. Original air conditioned car with compressor and all there. I know of shells in Silver City and Edgewood
