Bottle is a 10lb bottle. Standard with all kits. The NX kit is the only one that is offered for the 3V mustang from Nitrous Express. All the rest of the part numbers I am not going to look up. NX blow down tube, only one offered, NX Blow down adapter, only one offered, and NOS bottle warmer. If you're looking to see how much you're going to save it's considerable.
