The only reason I see a problem with the hacksaw idea is the area in which the bolt is. To **** close to the tank with little room to use the saw I would hate to scratch the tank. The good thing about the punch or chisel is the shock will quickly loosen it and you will be able to spin it out with your fingers. Just my take on it do what you like. I do agree with changing the bolt out for something else although I like the large head on the OEM one. I think maybe you need to lesson torque of the gorilla arms TD
