The foam itself fits perfectly, no issue at all changing the hard top out for the foam, it was very straight forward. I would recommend either the Kaizen knife set, or one of those electric heated foam cutters for a perfect cut, the first time. The knife set I had did not work as well for me, and left some messy edges that took extra time to clean up. But that's user error and not product error. 5/5 for Kaizen will be buying more in the future.
