Please evaluate rust

[Puma]

Howdy,

I've got a line of rust extending from the corner of the package tray down to the seat on both sides. There's a few small holes in the seat bottoms. The issue I'm concerned about is the seams where the panels join.

When I examine the replacement panels available they extend to the corner and I don't see any panels that actually cover this area.

I don't think the replacement A pillar/cowl piece extends far enough, not sure?

What do you guys think?

Puma... I've seen these attended by hand making the parts or the other option being cannibalizing another car where the structure/metal is sound.
