“Just want to say THANK YOU for your help with this! I couldn't believe the handle arrived Thursday (after ordering Wednesday). I brought it up to my dad's house Friday and just looking at it I didn't think it was going to fit....but it fit perfectly. So appreciative for your expertise and quick shipping! ”
