90-91 to 92-93

I have a 1991 da and i have no front bumper…I want to put a 92-93 front bumper but I’m not sure if i need the styrofoam from the 90-91 bumper to install it. basically im asking if i need a 90-91 bumper to install the 92-93 bumper.

to do the 93-93 conversion you need the 92-93 radiator support and foam

No you dont need to change the radiator support.

I was running cut 1990-1991 bumper foam, 1990-1991 bumper support with my old 1992-1993 bumper cover.
