Ram ball to Scotty mount

Im looking for a Ram insert into a Scotty mount. Ive seen an expandable insert type, but no regular splined model like Scotty would normally accept. Is there one made?

This is a RAM-351U.  I think they made another one that bolted straight through the ball and through the scotty mount. 

The RAM expandable ball mount for the Hobie sail mast has a tab that fits into the Scotty notch to keep it from spinning.  Once inserted and locked down, you don't need the spline part to rotate it because it's a ball.   

Ok guys thx. I didnt realize the expandable type had the notches and did not see the other one at all.

Worked for me.

Didn't know that existed!  I'll have to try it out.  Thanks.
