I can't get the top nut loose inside the engine well. The top bell just spins. I've tried putting some small vice grips on the top post, but it's too small to get a good grip. This is a crazy system. They shouldn't be this difficult.

The easiest way is to go through the wheel well with a sawzall and cut them off. Takes about 30 secs.

I was getting to that point. I don't doubt you, but what a crazy-ass way to build something.

I just did this a month or so ago. Spent 20 mins on the first side w/ wrenches, grips etc. Finally said screw it and cut it off. The 2nd side took 30 secs! LOL!
