What's the difference b/t the '71-'74 cuda floorpan versus the '70 model?

There's an AMD full floorpan for sale locally but it's for a '71-'74 cuda and mine is a '70.

They have a lot of differences.
The most important is that the 70 pan has a flange on each side that is vertical and welds to the side of the rockers; you make a weld on a vertical surface.
Teh 71 and later have a horizontal flange that sits on top of the rocker and and is spot welded on the top, horizontal surface.
They are not interchangable.

just the sides are different, but the rest is the same if you need a few patches
