I have only one thing to say; KROIL by KANO Labs.
Do a web search and buy some if you want to get the bolts off your self.
Keep them wet for a week or so before you do it.
Every other penetrate oil is just oil. I have seen DC Servo motors that
were under a side head and drenched in coolant with a rotor that was so
stuck that 60 tons would not move it. After a week it almost slid out on
the floor with a light love tap with a dead blow hammer.
OK that was more than one thing but it was one subject
