Dumb new Skeeter question number... shoot I lost track :).

Those stiffening braces under the deck lids on a Skeeter, are they also made of aluminum, or something else? They are carpeted, so can't easily tell. I assume the would be aluminum but figured I would double check. Have one of those spare tm prop mounts I splurged on during the TM sales, and seems like the perfect place to mount it with the included 1/2 self tapping screws...
