Mines the same as Rustys, a two tab. It fits pretty snug too. When I first got it I couldnt figure out how to get it off haha. Mine has a couple spots where the chrome is bubbling, but its very minor. Got it for $20
Got my cap and it is a perfect fit. Looks great, now I'm afraid to use it for fear it is stolen cuz its so nice. Time to switch back to the old busted one..Nah. but a little paranoid now. Argh
