Hello Team Titleist, I Picked up a 909 D3 ex demo from my local golf store 2 weeks ago. firstly I was wondering if  you can tell if the club head and the shaft are authentic.

I will include some picture below.

Secondly I was told that this club was used for fittings at Titleist Demo days therefor the surefit hole in the club head, the perosn in the store said it was used for easy replacement of shafts. The golf store told me that since then Titleist had Glued one of the ex demo shaft into the head, is it possible to have the 910 or 913 surefit sleeve fitted into this head?
