Yes and yes.
Considering your car is pretty old, to make it easier, I would just cut the fuel tank straps when you drop the tank. Once the tank is out of the way, you will see the factory fastening hardware used to hold the tank up and be glad that you did cut the straps. Most people can't unbolt the straps with the existing hardware. Its easier to cut the straps and remove the old hardware and replace it with normal bolts and nuts.
