This is a brand new paladin 150. There is one bolt at the rear that I can't get undone. There is something on the other side of it that is spinning but I have no way to access it. Any ideas?

This one:


My guess is there is a nut on the other side that was welded but broke loose when they tightened it.

Can't figure out how to get anything behind there and I can't remove the body panels without getting the seat bucket out.
