are the bumpers from an 04+ wrx a bolt on to my 03? i already have the new taillights... is there anything else i need to do to have an 04 look rear? thanks

 

i actually have done this converstion already, and you do need more than just the rear bumper off the 04. you will still need the new bumper brackets, and i believe there's some modification involved on the inner quarter panel. not too sure cuz my body shop did it for me.

 

I actually used my stock 02 bumper and modified it slightly. I just cut out a little groove where the curve is. Fits like a charm! Save that money!!!
