Based on what we know, they were .370″ tip. How long are the shafts? If you can measure the parallel tip section length, we could possibly give some guidance on trimming. If they are all different lengths, then either they have been trimmed or they are discrete length .370″ shafts. You might contact Fujikura. They made a lot of shafts for Taylor Made and they may have been the manufacturer, but can’t say for certain.
