the seats are very easy to remove. underneath the car, directly underneath the 4 corners of the seat are four holes, often times plugged with black plastic caps. pry the caps off w/ screwdriver, put in a deep well 1/2 or 9/16 socket w/ medium extension. easy as pie. if you have a compressor w/ air ratchet (which may be a bit overkill) it's laughably easy. take out the back 2 first, then the front near the tranny, then the front oustide. trust me on this, you'll see. from the top side, between the seat and the floor are 2 or 4 small rectangular plates, per side, make sure you reuse these properly, pay attention to their placement when you take the seat out. not as easy as a '72, but not hard at all. if neither car has the plugs, or if they are damaged badly when you take them out, order new ones from national parts depot. they are cheap.
what do you mean by rails? what else you got?
