Sammy Swindell, Johnny Parsons and PJ Jones have run that series this year too. Not to mention the outstanding regular drivers.
Leffler is like 7th in the points.
Saw the Silver Crown cars run at IRP back in about 1985 or 1986. Put on a great show. Haven't had the chance to see them run recently, but back then many of them were carrying the left front tire off the ground halfway down the straights.
