Yes those are the ones, they look really nice on your rig...
One part of the fastener (bottom section)seems to have almost nothing to grip when they are pounded on, ours did not even make it home from the tire installers, one went rolling into the ditch and the others were all loose so I took them off.
Our wheels were second hand and they are all scratched around the outside edges next to the rubber where the previous owner must have been putting the back on many times...
