I was trying some different settings on my 917D3, when I put the head back on, I tightened it with the Titleist wrench, but it did not click when tightening. At first I thought the screw was stripped, so I tried the wrench on my 917F2, same thing, the head of the adapter turns, no click.
I was able to tighten it using a png wrench, so I know its not the screw or shaft. I think my adapter is broke.
Where can I get a new one? Thanks.
