#1 Q:   My opening is 4 X 11 5/8 The specs say 11 5/8 X 5 5/8. According to that measurement it would fit lenght wise but not width wise. Is that a typeo? Should it be 3 5/8 on the width?
A:   The spec you are looking at is the overall size of the booster. The portion that slides into the opening is smaller and fits 4x10 openings. Not a typo. You would need the adapter plate for your size opening.
