In my experience changing these out really isn't necessary. Clearance isn't the problem, a bad angle of the ball hitting the guide on a left orbit shot makes it bounce when it shouldn't. The problem is clear from the slow-mo video:
Fix the diverter mounting hole below the playfield to move the diverter arm a smidge closer to the front of the playfield and your problem will be solved for $0.00.
