Nice updates
The seats: I assume the 19 lbs is w/o the brackets, right? Any idea on bracket weight?
The trunk itself on mine has been perma-stripped-out for a while now, but I have yet to move forward to the plastics just behind the seats. Will probably be coming up soon though, for the same reason (make it easier/cheaper for a local shop to weld in a 4-pt rollbar setup and attach harnesses, and then probably leave them off).
What about the wimpy stock bar/tube that goes across the rear interior? I'd think with even a 4-pt rollbar in place you've got far more strength than that dinky thing ever offered, may as well kill it right?
