Not tractor related but I'm sure somebody has some advice for me here 
One of our bigger tanker trucks Tank tie downs snapped. Not uncommon. I have changed probably 10-12 over the years.
Except this was on one of our older trucks. Meaning the bolt has been in there for 15 years. Went to go take out one side and no go - same with the other. Was able to grind off the head and get the shafts off. But I still have the bolt into the aluminum stuck. Oxidezed/welded together for better terms. No threads - the bolt just goes through a hole in the aluminum block. No amount of hammering or impact wrenching is making it budge.
I need them out to get a new tie down in place. Already tried heating them up - with kroil. No go. Tried some wax - no go. Unless I need to heat them up longer and use more kroil and wax?
Pictures of the offending bolts (terrible spot one side is in) and then another tie down thats in tact so you guys get a picture of the problem.
I can grind them flush and try to drill them out. But they are grade 8 on one side and grade 5 on the other. I know its gonna be a bitch to drill.
We have a plasma cutter - I was thinking grind them flush and them hit it with the plasma and burn it right out? Gonna splatter a bit but should be able to blow it out? I have cut metal before with it but never tried to blow out a gridned bolt before. Little leary of using the plasma cutter on the vehicle. I can get a good ground, but lots of electronics on the engine and ecm computer I would worry about if the plasma doesnt ground good and travels to find the expensive electronics.
Any advice? I know lots of people here have older tractors and must have had tons of stuck bolts before. I can almost always get a metal bolt out of metal. But moetal bolt stuck on aluminum is got me stumped.
