Hi, thanks for the email.
The F6B seat is a notoriously difficult install. What usually corrects your issue is to push the washer-spacer through the vinyl into the seat, so that washer is now behind the exterior vinyl but the spacer is still inside the seat. This should allow you to close up that gap.
If you still have issues, please reply with photos.

I have yet to do this but immediately asked why this would be required on one side and not the other.........I guess he has been busy. YMMV
