In June of 1965, Dick Dunshee became injured in the first lap of a 75 lapper at the Grand Rapids Speedrome, he asked Bob to drive his car, and after starting last he passed Bob Senneker on lap 52 to take the lead and win. The following month he started racing a super modified for Bob Snyder. He ran at Hartford, Grand Rapids, Dixie and Heidelberg, PA. He won the 100 lap season championship at Hartford and also the Carter-Nelson memorial race at Auto City. He ended the 1965 season by finishing 6th at Heidelberg in their big finale.
