Yes, I think it helps. I think I can visualize what you're trying to say. So for the driver's side, you need to pull the lever back (towards the rear of the car) in order to adjust the seat. Is that correct? Then for the passenger side it's the opposite?
Yes, that makes sense too. So when you release the lever, the seat should spring forward, correct? I'm assuming that's to facilitate moving the seat sot hat people can get into the back.
Both sets of A-Body tracks that I have, there is one with more "overhang" than the other. I'll take some "straight on" shots when I get home tonight so that maybe this could help out other people as well.
