Its a winterization hatch. Details west makes one, dont remember the part number. Theres probably some others as well, not something you have to scratch build.

I don't remember if it was DA or DW that made them from plastic, with an etched screen over the fan area.  That would be the one to get, as the other is a metal casting that requires removal of the radiator fan.  SOO ones were a bit different, squared up corners account being fabricated at Shoreham Shops.  You could follow the prototype and make your own box, adding a Plano etched screen.
