After removing the fabric seat I attempted to remove the cargo "bag" behind the seat. I found it captured under the seat pan even though it seemed to be velco'd in as well. I found the seat pan is being held in by two dozen zip ties. I also noticed a bunch of small holes in the pan. So now I'm wondering if the pan was meant to be screwed in or held in with zip ties? And I'm wondering if the pan should come out anyway for inspection.
