While doing this, I thought or something easier, but I have neither the skills or tools to do it. If anyone can help me with this, I'll definitely pay for the services. But I was thinking of welding off the parts in blue.Once, I have easier access to the bolt, I can just angle grind off the head of the nut so it should just slip out. If anyone can help me out with this, I will be very greatful and happy and godknows what else!

The nut in question!
