These hybrids were a .370" hosel bore. It is possible the bore could be a little tight. Generally .370" hosel bores are close to .375". It is also possible that the shaft tip is larger then .370", especially with graphite shafts. A .370" tip size graphite shaft is made to .370" then painted and clear coted and I have measured shafts in the .380" range. Many time the shaft has to be sanded before it will install into the clubhead.
