Canoe foot brace slider

Anyone have a dependable lightweight system to adjust a canoe’s trim by moving both the seat and the footbrace in unison?

In particular I am working with a Wenonah solo that has the footbrace and floor-mounted sliding bucket seat. I have seen a few systems but I am looking for more ideas.

My old Summersong has the seat and footbrace linked by two rails that ride between guides glassed into the bilge. Works well, but probably not applicable to your situation.

I think J&J Canoe in NY has a kit that might let you do what you want. and scroll down.
