Similar to the taxi/police interceptor models? I'd say your best/cheapest route is to find someone who builds 4x4 bumpers near you and tell him/her what you want. They have the pipe benders and experience to fab up something that'll do exactly what you want- and no one else will have something like it.
Hey! I'm not toothless I think I might still have a 02 out there. I got a few trying to fit them to my 87, they just didn't fit right. I also make them, I have a nice size shop here and welding in highschool. If your interested.
Go to eBay and look up "push bumper". There is always at least 2 up there for the Crown Victoria. They are the Code 3/Lectric Lites bumpers. Prices are usually good, but the shipping is usually around the $20-$30 range because of the weight.
