"...Was Nicholson the OS/S R/U at 61 Indy with that car or dont we know?..."
In the Jr. Stock book, on p.14, it says that Proffitt "buried" Dave Strickler's 409...with an astounding 12.55. I suppose that means that Strickler was RU. Not sure. Could have been in an earlier round, I suppose.
One of the books says that Arnie Beswick won S/S. Don't mention the RU. Maybe that's the year Stan Antlocer was RU, in S/S.
