According to the HD catalog, Chrome Swingarm axle cover for softail pn 47596-91B fits 87 - 07 softail models except FLSTS. There are several saddlebag pn's that will exclude it being used. There is also a chrome HD script cover (two different pn's), and a black cover. 08's and up have different part numbers.
i have the scrpit axle covers, but those(42069-08) caught my eye. i know about the covers for the 07's just wondered if anyone every tried to bolt those up to an 07, if only the axle size changed, then it should fit, might give it a shot
if i recall the Script Covers in the HD Catalog doesn't say they will fit the 07's...... but they do. Could be the case with the ones that you're looking at
