71-74 charger hidden headlight Help!

[74secharger]

Does anybody know if you have to use the 71-72 bumper or can you use the 73-74 bumper on a hidden headlight assy

I put 71 superbee hide aways on my 74 ralleye bumper. fits fine.

should fit but you might wanna check on if 72 and below used vaccum vs electric motors. I know they switched but dont know what year.

I'm pretty sure 66-74 are all electric. At least 68-74.
Even newer. ...and most motors interchange.
Even C body, all the way to Magnum IIRC.
