I just got a new front bumper plain old plastic oem replacement and it wont fit. The width is right but it looks like the top mounting point and bottom lip mounting piece need to be heated up and molded a bit to fit properly, so I was wondering if its possible to heat it up and how. My cars in pieces right now and I only have tomorrow to do it so any help would be appreciated

 

What year/model is the car? you will have to post a pic to show exactly what the issue is. Aftermarket parts can have fitment issues.
