Are all floors the same?

it's been a while but the only crossmembers i recall are under the front seat. they are a heavier gauge metal and cleaned up ok on mine

There's definitely a cross member under my floor. It lands under the rear seat foot wells. Mine was totally unsalvageable and is now completely cut out on both sides of the car.

That's looking good, can't wait to see the welded in.
