Look at
www.craigslist.com under the Auto Parts section for cities near you. This is how I found the 2 possibilities for my truck.
If I can use the bumper off of a tow pkg. truck, I should get one for less than $150.00.
I also found a guy in Houston, TX on E-Bay. He had lots of used bumpers. He was priced at $109 to $189 with free shipping. In my year, all of them had scratches or dings. This is why I am looking near my home.
Good luck
