I may be wrong but it's going to depend what model Ram you're rockin'. I love those bumpers as well as the ones from other brands but I still haven't found one for the '10 1500. It's really easy to find them for the 2500/3500's though. If you find one, please let us know.
There are some guys out there that have retrofitted a bumper for a 2500 onto their 1500 and were very proud of it. Personally, I thought the work that I saw looked like chit. Just my .02.
