I am looking for a set of rear frame rails for a car i am going to be doing work on---a '73 Road Runner. I know because of things like emmisions routing and what not the rails changed, but are there any major floor pan changed between a 71-4 Plymouth B-body? My concern is that they match the floor contours more than correctness for the car as this car is already hot rodded and has a fuel cell and such.

I've had 71, 72 and 73 rails side by side and only difference I saw was 71-mid 72 has slots in the left rail for the 4 vapor lines.
Not sure about the 74's but think they are the same from what I've seen.

shape will be the same and will match the floor countour. Not a problem on that.
now, about the cut outs, not sure though.
