Oh man, that one is really bad. There is a chance the mustang pans would fit if there are not any falcon pans made since they were the similar/ same f-body chassis.

you mentioned inherited. if the car has sentimental value it may be worth it but otherwise if there is that much rust in the floor there is probably rust in other places as well making the repairs much more expensive than the car is worth.

Personally I would part it out and take that money to get a better base to play with.
