When the seat puck is in it's home position, it's locked there via leverage and even with the track disconnected, you can't pull forward, or down. It's also attached at that point and reinforced with a 1/8" steel bracket that is bolted with big heavy bolts to the uni-body. It's not going to give.
Other than seeming like a pain, it's supprisingly simply to pull the side panels off the car and get the track out of there. You need a 10mm and 8mm socket plus a philips screw driver. You have to pull the bottom seat cushion out. If you haven't done that before on a car, just pull up near the front edge where you can feel resistance. It's got a steel rod that slips through some hooks and it'll pop out. To put it back in, push the seat into position, then push down on the cusion while you pound it back. Ya figure it out.
Some of the internal parts can be swapped from left to right.
