Son is doing this, has a question, the Marlin stock is polymer and has just one screw in the trigger guard. The Boyd stock is wood and has 2 screws in the trigger guard. Is it just as simple as drilling a hole for a second screw in the Boyd's stock? Does he need a different trigger guard? He has searched youtube for a video of this conversion with no luck, any and all suggestions welcomed. He has the rifle, otherwise I might be able to provide a better description of what is involved. Thanks for letting me pick your brains.
