Hi, I have a 2004 Malibu LS and I was wondering if there was any way to attach a bash(police) bumper to the car. Here are some pictures of the car if it helps.

 

those poor rockers.
that car looks like it will just fold up in an accident. I probably wouldn't add any more weight to it.

 

yeah but zombie crushing is fun.
you would have to cut and modify the front fascia to get to the structure of the car.

 

Take a look at a baseplate for RV towing the Malibu. This video shows how to install one on a 2004 Cavalier and may give you some ideas.

Here's the part number: https://www.etrailer.com/p-BX1647.ht...hhmodel=Malibu

It would give you a mounting plate connected to your "frame"

Another brand is Roadmaster. This page has a link for the installation instructions that would be handy to look at:
