I didn't really know where to post this so I put it in here. Anyway, my lumbar knob is broken (like many other peoples I'm sure). Does anyone have any methods to get it back in the seat so it's not just hanging there. I have the screws and black plastic pieces that broke off, but I don't know how I would get them back on the knob and then back in the seat. The hole for the lumbar knob is very small. Anyway, give me some help if possible.
