Although I liked the way I originally installed the seats directly to the seat pan for weight savings, I realized that I couldn't get them back as I needed for my legs. So, I broke down and installed the in-flight adjustable seat sliders. They are heavy, but I can get the seat quite a bit further back. I can also install with some bushing to tilt the seat back a bit as well. I think I may eventually rebuild the seat pans with the seat back brackets riveted at an angle to get the seat back angle the way I want it. Once I get the upholstery in there I should know.
