Is it grill or grille? ? Either way i need a right side insert for my 84 delta 2 door. A guy on fb has both left and right side but from a 1980 delta 4 door. . . Will these parts swap out with out any complications or customization? TIA for the help.

Yes, the grill from an 80 will fit your 84. There is no difference between 2 door and 4 door.

Grille.

Grill is a cooking surface. Grille is a grating or screen.
