It was an aftermarket catalog and I can't find the ad now. I'm looking at a bunch of them on ebay and they all show only with or without fogs, nothing is said about ABS.I checked the 2001 Mopar LH parts catalog and they only show 2 bumper covers for Dodge. One is with fogs and one without. Are you talking about an aftermarket catalog or something else?
These are the two numbers in the 2001 catalog I have:
04574834AB 1 D P, X
04574843AB 1 D H
It's item # 6 in Figure 13-210 of the Frames and Bumpers section.
