Hi Brian, I ordered it from grasshopperlimited.com : Yamaha Warrior - GRASSHOPPER LIMITED
However I believe that this backrest only works with a 2 piece seat (seperate driver and pillion seats) because the bracket from the backrest slides in under the pillion seat. If I remember correctly, you have a 1 piece seat.
I'm not sure what your last question is but with the backrest, I feel that I'm not leaning forward to reach the bars, meaning the backrest kind of pushes you forward, if that makes sense.
