Yep the only tough part is along the trans tunnel where you stitch weld it. The rest is plug welded along the inner rocker panel, lower footwell and just behind the seat after you drill out all the spot welds. If you raise the vehicle on one side you can can complete the welds underneath. If the car hasn't been blasted then most of the deadener will be loosened enough from the inside welds to clean off easily with a wire brush (it also has a tendency to catch fire too but goes out quickly) simples.
Great to see some pace in this project.
