the STE has the lights that run acros the front that attaches to the bumper. I do no like this look and wanted to know if i can take a normal grand prix bumper with the trademake "holes" and replace it. Would it bold on the same way, would it fit? Anyone know?

Well the bumper will fit to the car body since GM do not build different underbodies for the same car type/different models. So you should get the whole facia not just the bumper because the bumper might not fit with the grill you have unless of course you want to mod the bumper a little to match it with the origian facia. If not replace the whole thing
