Here's my first try at changing my seat a bit. I will redo the seat again, recovering it and making the passengers part wider. Wide enough to cover the cut edge of the grab bars. I can take more pics when I go to disassemble this first try; if anyone is really interested. For my first attempt all I did was cut the back rest portion of the seat pan off at the bend. Squared my edges and reapplied the cut piece horizontally. I added on to the frame underneath, extending the frame pipes under the backseat by 3-4". I used the same cover & the same padding. I added 2 little pieces(3.5") of aluminum bar stock mounted on each side of the seat. These line up with the grab bars rear screws to hold it all down.
