Errrrrrrr..... 😡 Im replacing the stock leaf spring with a sport spring. I've got the old leaf spring loose with the tension off of it. I've got the passenger side lower A arm down but the drivers side must be possessed. The two bolts that hold the lower A arm to the cross member will not budge. I have the nuts off. I've used heat, beat on it, prayed, you name, I've tried it... it's like it's welded on! Any suggestions?
