I have a set of 1969 MT Tourneys I inherited from my dad. These are the clubs I learned to play with. I had the irons reshafted years ago and the guy did an okay job, but he told me the shaft tips were an odd size so tapers were too small, but 370s were too big. I’ve been a club maker for 30 years and have decided to reshaft them again and do a proper job of it.I don’t have an old aluminum shaft to measure. Any idea what the size is??? Thanks from the new kid.
