Yerf dog GX150 spider box seat bracket

[FireMedicKK]

Just wondering if there is a way to tighten my seat bracket for the drivers side. The problem isn't that the seat slides back and forth (it does that fine). The problem is the left/drivers Side bracket is loose and when I make turns the seat almost comes off the bracket (kinda like falling to the right). I don't know if there is a way to tighten it or order a new bracket or seats? Any info is greatly appreciated. Thanks
