Eguller This is a really 'who knew'. Found them buried under some Winns. 10 new Tacki-Mac 58r grips and I'm going to throw in a slightly used Super Stroke Flatso 1.0 I believe they called these 'arthritic grips' but not sure. They are approx standard size and a 58. I really don't know much about them but it says 'Tacki-Mac USA' on the butt. Hmmmm. Shipping cost only for $15 shipped TYD. Lucky 13 sale and you never know what you'll find in the box....PM for PPal & questions. Thanks for looking.
