Trunk Lid question

Hey guys, I'm slowly working my way around my '63 valiant and am tackling the major body damage. my trunk lid is the next target. By the attached images am I better off trying to locate a lid or is this an easy repair? I know i can sand out and rust prevention treat the bulk of the rust, but that hole is fairly large and in a bad location even before exploring the extent of the damage.
