I have two balls that were originally drilled for another right handed bowler that were plugged and redrilled to fit my left hand. In neither case does my track cross a plugged finger or thumb hole. I suspect this should hold true for you as well, but looking at the position of the pin to the original holes the previous owner had a some what different layout on these balls. Most of the time the pin is just above or just below the finger holes and not very far from the centerline of the grip. On both of these balls the pin is above and to the right of the ring finger whe looking down at the ball with the thumb hole closest to you. The current drilling has the pin just over ring finger.
