Seat track questions!

Alright guys, I feel pretty dumb but I cannot figure out how these tracks should properly go. They are 66 dart seats going into my 65 barracuda. (To allow for a coffin console) Sadly, I do not even have the original holes in my replaced floor to match them up with.

Is there a drivers/passenger difference and does the rail with the lever goe toward the center or the doors of the car? I could scarcely even find pictures of any seat bottoms with rails attached.

(Ignore the cat in the seat lol)

Thank you for the help!
