I am trying to find a replacement seat. Ive been told the trailblazer 250 seat is the same, but can not find a used or new anywhere. The one i have is broke and will not stay in place. Up top where it connects to the plastic (near gas tank) keeps popping out. The under side is split. What can i do or where can i look for one? I can re cover the seat just need a good plastic and working clip that attaches the seat. Thanks
