ok so i have nearly got my pulse adrenaline broke down to a bare shell to prep for a repaint, but i have one nut stuck in the engine mount and doesnt want to move, can anyone help?

also i am wondering(this is a big ask) can anyone tell me what bolts make up my bike(pulse adrenaline) apart from the engine bolts as i have all these, all the rest of mine seem to be corroded
