I have a Gandy big g or hustler not sure which model it is. It has the fiberglass and rubber ball return and i cannot figure out the intended way to attach the gully extender to the pocket and ball return. The person I bought the table from screwed the pocket liner and extender together from the inside of the pockets, but that will cause damage to the balls so I know thats not right. I am trying staples from the back side of the pocket, but that doesn't seem like a very good hold... Anyone know the right way to do this?
