OK, so the mirror is '71-'72 Mopar B-body and '71-'74 Mopar E-body. The B-body mirror changed in '73 (taller base with wider-set mounting screws).
The remote bezel is for '71-'76 General Motors B-, C-, and E-body.
It's the hot setup for folks that just gotta have 'Cuda mirrors on their Toronado or Hoop de Ville!
