I ordered this one from FMF, wanted something that wasn't logo'd. Great guy to deal with and well made, just haven't had time to put it on, have to pull my PSC bumper back an 1/8" to clear the tire carrier when closed as this one is punched out 7/8" to accommodate for the vent.
You could just make your own like I did.
