Core thickness for hatches and deck on 1988 23CC

[Benzzino]

Does anyone know the core thickness on the hatches and the deck on a 1988 23 CC? I have one side of the aft deck soft that needs to be replaced, the live well hatch is bowed down, the small hatch over the fuel tank as well as the large hatch over the fuel tank and under the console. Also, if anyone has any experience with cutting the core out of the bottom of the hatches I would appreciate any advice.
