I had ended up ordering the pans off eBay. They came the next day after ordering and were nice quality. They were the full pans so I had more than enough to cover the cancer spots after they were completely cut out. It was a bit more work so if I have to do it again, Ill used an entire floor or half. I sealed everything up with por15 on both sides of the floors and then a layer of fatmat for sound deadening on the inside.
