You might fish around upon their site and find the exact part. Surely it will lead you to someone who will. Best wishes!

I'm sure that I have a few of those around. I could dig one out with the clamshell ball and ship it tomorrow for $12.
The price on Pelican is pretty good, but wouldn't include the ball head (which is probably also available if you look up the part number).
