Need a Mopar bumper expert

Drill to size, dremel some, then a small triangle file? I just wanted to save weight on mine. Should have never even thought about it. Cost me money I'll never see, probably won't do it, as I think it's maybe 10 # per side. I dunno.
I have projects that have already spent the money on and I still can't get around to doing it. All of them are too involved and I'm getting lazy. Not that this is an involved project but I've had the bumper for years and just recently decided to put it on. Tired of looking at the sorry repaired one. But what happens; it's the wrong part. Tell me that's not a blow. That's $300.00 down the drain if I can't find out what this thing fits.
