Most agree that the bracket is there to stop the seats from moving too far forward, all cars have them regardless of seat style. Probably there as a safety stop to prevent the seat from knocking the car out of gear on manual trans cars.

As far as the second page on the wiring, I looked through my book and those pages have been removed (even the one I copied and posted before) I must have pulled them for something and now can't recall what I did with them. I'll do my best to dig them up.

Cars looking great!
