Tom was right on with advice on this mod. It takes less than a hour and is not hard if you have the right tools. I removed only the left side ristpin lock and pushed the pin out leaving the right lock in to keep from getting the piston turned around and trimming the wrong side, I know this might be overkill but works for me.
