here is the response i got about the bumper from Iron Bull.

Hello, you can ad any of the 16 different bars from the 2 Grille Guard pages of our web site , just tell me a name of the bar that you like and i can give you a cost of the bar as well , but for now i will tell you about the front base bumper , it will be all made of Deer Splitting 3/16th plate steel and will come ready to install with our black shield paint , all the winch hook ups , the D rings are welded inside and out , also it will have 4 , five inch light hole buckets with a tab so you can install extra lights ,,,,,,,,,,,the normal cost is 1600 plus 350 shipping in the USA, to go right to your House or Business address it will take 3 weeks or less to be made and shipped because we make 40 to 50 bumpers a week ,,,,,,,,,,,, thanks and let me know if we can help outfit your truck ,,,,,,,,,,

Fitment looks okay....although I wonder what you can see from the front/sides as far as the undercarriage; the stock bumper goes much lower than this...

Here, put the pics in the thread for ya:

 

Do you offer also bumpers for the 98 Navigator?
