I'm working toward fixing my seat hinges and part of the solution includes replacing the rubber seat bumpers. I'm trying to figure out the best way of removing the old ones - the stems that are stuck inside specifically. I think once I get them out, I can push the new ones in. Do I have to disassemble the seat, or does anyone have some trick to getting them out? I thought about using something to push/pull them toward the larger holes - like a hemostat.
