Are Petitt's "3G DOOR SILL SCUFF PLATES" the same as MAZDA'S aluminum accessory sill plates? If not, would anyone happen to have a pic as I can't find one on they're site. Some of the snaps on my OEM black plastic ones have broken and I was thinking of doing an "upgrade". Petitt's are pretty pricey, but MAZDA'S alum. sill plates seem to scratch pretty easy. I was thinking that if Petitt's design or material was alittle more resistant they might still be worth it. I did a search but didn't have any luck. Thanks.
