I have an old set of these irons that were my fathers. I recently gave them to my son to use as he passed my old ap1s to his sister. It was meant to be an interim set until he could get new t series, but he loves them. He had regripped them all, however one of the tungsten weights in the 9 iron has fallen out. I bought a used 8 iron in hopes of taking it out and putting it into his 9. Does anyone know how to remove the weight and replace it into the 9? He really enjoys playing with his grandpa’s old clubs. Thanks
