Replacing Integrated Fridge/Freezer Base panel

[CoffeeCake]

Hi Everyone

I am new here and seeking advice. I need to replace my integrated fridge/freezer, I bought a new unit along with installation, when they delivery came, the fitter noticed that the panel that the fridge sits on is weak due to water damage and recommended replacing it before fitting in the new fridge/freezer. I'm attaching a few pictures below.

Red marked panel needs changing:


What would be the best way to change just that panel?

The base in integral to unit so unless you want to remove unit and replace cut thru the centre of the base and break out the pegs holding it, replacement will have to go in with repair brackets and you will have to re attach the legs.
