Lowest rod mount for a Manfrotto 577?

[Alpha Beta Omega]

I'm trying out a configuration where I have to have a Manfrotto quick release as low a possible on the rods. Where can I get such a lowrider?

Flip this one upside down. We can meet if you want to try mine.

Does the holes match a 577?

I thought the 577 have a additional 3/8" underneath but maybe I recall wrong.

Yes it does have a a 3/8" so I guess it'll work.
