And the verdict is... Aftermarket.
They look pretty nice actually. But they have burr edges in many areas. They are missing the welded in washers at the frame mounts. The metal feels just a touch thinner and it weighs 1.5 oz less than the original. The metal doesn't quite line up right on one of the top license plate holes. Slight difference in the shape of the little notch that's cut on the side of the part. Last thing, the chrome is different. Too smooth and shiny. The grommets are prolly standard electrical grommets, and the metal spacers are aluminum.
Bummer.
But again, they're not too bad. If they would get rid of all the sharp edges they'd have somethin.
I'll be lookin to unload them, (I have 2) if anyone's interested.
Original part is on the left in my pics.
