70-71 have two screws that hold them to the grille . 72 and newer are twist in sockets same as 72 and newer plymouth or sharkstooth grille for 71. I have 71-72 dart sockets and pigtails. extra for my Demon $40.00 + shipping for a pair. Good condition not rusted or corroded. Flat double plug with a separate ground wire. Let me know I have them in grilles upstairs and would have to have guys get them off.
