VERY strong Tool Box/Aux Fuel Tank, was used for diesel fuel.
I do not have the adapter kit, but you can make your own for MUCH cheaper than they sell for, and it will also work better than the kit you'd buy.
I also do not have the keys, BUT, "The Lock Shop" can and will make keys, or switch the lock cylinders out for a fair price.
I cannot deliver, for I have no vehicle at this time.
