+1 on what Steve said, I prefer the wedge type over the piston type.

I have one from the CDC tools and it is for my Heave 10" Southbend. I have a 10" logan that I just got and will check the tomorrow and post the results. I do know that you will have to modify the T nut. I really like the one I got from CDC tools. Works great.
You never did follow up................
What one did you get, and did you get a chance to try it on the Logan?
