Floor pan interchangeable?

I just picked up a 76 Feather Duster. The floor pans in front are in bad shape. On a trip to the local yard I found a 76 Dart 4 door That for the life of me I can't figure out why it is there. I think it really only has the 37K miles on the odometer. The interior is perfect (tan if that is what you are looking for). Can I cut the front floor pans out and use them in my Duster? The really bad part is where it slopes up to the firewall.
