I have a Munch mount but I'm sure it will work with the Groundpounders also.
The first option is cheap and fast. I simply replaced the 2 screws that come up through the riser with a couple of 5/16 x 2" button head cap screws.
This leaves plenty of screw exsposed to screw the quiver mount posts down on to.
This set up was very rigid and would work fineThe quiver mount bracket sits about 1/4" higher doing this but is not really an issue.

I work at a mold shop as a cnc machinist so I have access to material and machines so I decided to make myself a set of new aluminum posts that would match the radius of the top of the S5's.
I spray painted them flat black to match my Munch mount.
In order to make this setup work I needed to drill out the threads in the string stoppers to pass the 5/16" screws thru into the new posts.
The new post where made shorter to make Munch mount sit at origional height.
