Here are two pictures I snapped of how I had trimmed the core support to accommodate the P38 steering box prior to stretching the frame. I do not know if this would work with the original radiator.
Today I started removing the entire radiator support. Also the hood latching plate. I will need to use hold down clips or a strap on the hood.
A leather strap would look pretty cool. We shall see. My wife gets to make most of the styling choices.
