On the 1957 Chevrolet station wagons, I believe that their was no carpet on this rear seat riser , and it was either painted the exterior body color, like on my original Surf Green 1957 handy man 150 two door wagon which had a rubber mat , or this metal riser was painted the carpet color like on a Belair wagon. I have seen carpet on this riser, but I don't believe that they originally carpeted the riser.
