Hello,
You can start by getting a quality lubricant, like PB Blaster or better and soak the heck out of them and leave them overnight. Get a quality 1/2" drive 6 point socket on them with a 1/2" drive ratchet. Next get a strong two or three foot pipe and slide over the ratchet. This is what is known as a "cheater bar". The longer you can make the cheater bar the more leverage you can get on the ratchet, which is turning the socket, which is turning the bolt. What did Archimedes say, "Give me lever long enough and I can lift the earth", this is the concept. It should break the bolt free. Get back to us and let us know what happens.
Thanks,
Alex
