I’m trying to re-shaft a Ping long pickemup putter with a shorter shaft, the shafts in the catalog show .370 or .355 dia. is that inside or outside dia.? My putter has a stem which goes into the shaft and measures aprox. .335 OD, if the catalog dimensions are inside dia I can always use a shim on the putter head stem, what diameter shaft should I be looking for?
