Toilet has been in place since 1970 - 37 years.
Needs to be dis- assembled and removed for floor work and painting of walls.
One tank bolt (brass nut, brass bolt) spun off as free and easy as you could want.
Other one is very tight against underside of bowl flange, though you can get a box wrench on it. Wont budge at all, whether I try to turn the nut wih the box wrench r he bl with the real big screwdriver.
Before I try to work a Dremel cutter in there to split the nut, (I'd really rather not be lying on the floor looking up at the nut, even with the eye protection, trying to grind through the nut and not screw up the bowl flange) has anybody got any ideas on what might loosen this thing up?
Thanks in advance.
