Thats Victor bringing down the old tank. Some tricks you should know. The bolts are carrage bolts that come down through the wood floor. Spin them and life is not going to be fun. We sprayed them with PB Blaster the night before and then clamped vice grips on them so they would not spin---we still spun one. This whole operation is a little tricky if you dont know what you are up aginst.
