Hybrid shafts usually are either 41 or 42 inches and are then tipped the required amount to match each specific hybrid and once installed in the club the shaft/club length is cut to the required length. The listed measurement of Titleist clubs is the length of the shaft from the butt to the ground with the finished length being longer when you add the grip butt cap- an addition which varies approximately between 1/8-1/4". If you wanted to know whether a previously cut shafts will meet the required/wanted length of your hybrid you would add to its length the distance from the bottom of the bore to the ground to verify that it meets your requirements. Of course if you have the shaft in hand you could insert it and have it measured to see if your required length can be met.
