If you are replacing it with the stock grip, any Titleist pro shop can order the grip for you. 

The stock for the studio stainless was the studio design right?  If so, go into the store on scottycameron.com

Stephen:  I believe you can order an individual grip from Cameron and put it on yourself (or have your pro do it for you).  They're pricey, but there is nothing like a Cameron Cord grip.  I like them so much I put one on my Taylor Ghost putter (I don't like the Winn that comes with the Ghost).  My Scotty is in time out right now (more an me issue than a putter issue)  I'll eventually put it back in play.  Just click on the Cameron icon below and go to the store.

Good luck!!
