floor pan diffs

[64longroof]

Have a chance to get a 72 Duster floor pan 2 door, and wonder how much work
would be req'd to mod it for a 64 dart, 4 door
To my memory, the hump seems larger in the later car.
I don't have the 72 in front of me. Waiting on pics, but if anyone has worked with both early and later floor pans, I'd appreciate input.

THanks

Won't work! Too long and too wide. Seats bolt different and so on. Two different cars all together.
