I've got an otherwise tight 60 but my rear seat latches rattle going over even the smallest of bumps in the road and it annoys the hell out of me. Maybe I'm too "A type" but I'd like to try and solve this. I put surgical tubing over the male dowel on the seat so it wouldn't be metal on metal as it locks into the latch when closed and this did help a bit. Now it seems the bar that goes along inside the seat and the plastic levers are a little loose. Can this be tightened somehow?
