Seats - Modifications
With the 4-place a means to easy access to the rear seats needs to made.  I reinforced the seat sides and added hinges. These work fine and are rigid.
Embedded 1/4" phenolic in the lower section and used flox in the upper.  They are solid.
  Still a work in progress.  Because the seats fold forward I am working a design that is simpler to build and attach to the seat rails and easier to add cushions and upholster.
