There's an extra plastic that sits on the departure ramp next to the "Sky-Taxi" decal. When I was taking this extra plastic off of my old ramp, I could have sworn something fell off of it when the left screw was removed.

Can anyone confirm whether or not there's some kind of plastic spacer involved with the way this extra plastic attaches to the ramp?

Also, I'm not sure the screws that were used by the previous owner are the correct screws. Can anyone confirm which screws need to be used? I don't want to damage my new ramp by using the wrong size screw.

Thanks!
