yea depending on how much you cut off and how much they tapped you can pop them back on. Best done by dipping grips in boiling water so they expand and popping them back on. Glue should not be manditory
some poles have a wood plug at the top where the strap screw goes in. chk that out. if u have that pop the wood plug out with a screwdriver & hammer or something and put it into the new cut pole.
