Well, that part number seems to match up with the correct bumper for a stepside so that's a good sign.

You're welcome. After looking at a fleetside bumper and comparing it to the one in your pic, I am going to retract my earlier statement about yours looking like a fleetside bumper. Although I thought it looked a bit wide, I don't think that is the determining factor.

The difference I noticed is at the outer corners. The forward facing edge of your bumper appears to be straight across. A fleetside bumper on the other hand has small notches at each corner that allow for clearance where the lower/rear corners of the bedsides protrude back beyond the rear cross sill.
