Old Super Tricks with center covers

[copo69]

John's right..Cragar accessory. They advertised them usually with their chrome "Smoothie" wheel and also could be used on painted stock wheels. I don't remember seeing many of them in the day but they're in the old speed catalogs. You see them used on some of the early super trick wheels mainly on the prostockers. I always speculated they were maybe used to strengthen the thin super trick's center.
