4 Door Bucket Seat Help

I bought a 4 door 74 Valiant last week to rob some parts from. The main thing I wanted was the factory bucket seats in them. I tried putting the driver seat in my 73 Duster tonight and realized the tracks are quite different. The tracks on the buckets are made to mount to a flat floor, but the Duster has the angled hump on either side where the bench seats mount.
Do I need to just buy 2 door bucket seat tracks and they'll swap over to these seats, or am I out of luck on these seats? I'd like to find out before I junk the bench I have.
Also is there any easy way to make the seat backs fold forward for rear seat access, or is messing with that asking for trouble?
Thanks a lot,
Jon
