I recently had some work done and when they replaced the engine covers under the queen bed they left out some fasteners and buried others in the rug without the flat washer.
I'm looking for someone to take a picture of the screw locations for the engine hatch located under the queen bed so I can confirm what is missing and what is going to have to be located.
Hope I got this right, I marked the screws with green tape. I noticed that the screws are not regular in placement, so it seems that placement was up to the installer to estimate position. There are eight screws, total. Hope you have a power screwdriver or a strong wrist.
