My cousin has a 1988 Chevrolet z24. And he has a 1992 Sunbird Convertible. He wants to change all of the z24 bumper covers and etc over to the Sunbird. What all has to be done?.

bumper supports have to be changed, then the bumpers will fit on. i put my 89 z bumpers on my 93 bird and i was having trouble at first but then they went on. also he is going to have to switch trunks to keep the liscense plate holder or just bolt the liscence plate to the bumper and put some lights next to it. the side skirts i havent tried to put on yet but im pretty sure they just bolt to the car. youll have to drill into the body.
