you need a air gun, that will get them off of there.

yeah we tried an impact gun and we got the very top bolt off and the bolt on the left side of the car (looking forward in the car). But we couldn't get the bolt on the right side. We tried just about everything. So tommorow i think we are just going to take a hack saw to it. Unless anyone else has another suggestion. By the way now the bolt is stripped.

A breaker bar with an extension...like a hallow bar...I used a vacuum pipe extension...

Dont try it too many times cause you will strip the bolt....make sure its on there good and push hard on the bolt then try and loosen the bolt

If you have a torch heat the nut or bolt red hot and then use your impact gun. But if you don’t have a torch just go for a drive that such make the bolt hot. You are just using heat so the bolt will expand.
