PLEASANTON -- For the second week in a row, Kerrville’s Greg Dinsmore was involved in swapping parts at I-37 raceway. This time it was an axle plate he lent to another racer. Last week he won the Modified race on opening night using an engine borrowed from Bill Pittaway. Pittaway went on to finish second in the IMCA Modified last week, and chased Dinsmore to the checkers again this week. . . .
