New Rear GT Bumper

I am looking to put dual exhaust on my V6 mustang and I was wondering if anyone had any suggestions for the cheapest place to find a take off rear GT bumper for my car. I want to take it to a shop and have it painted and put on my car. Thanks for all the help.

Look in 5.0 magazine they have a company ad in there and all they do is sell GT take off stuff like exhuast, rims, hoods bumpers etc.., Good prices, sorry I can't remember the name but when you see the ad you'll know what I'm talking about.

The place's name is Mustang Parts Specialties. The web address is www.stangparts.com.
