Golf, getting those bolts out is one of the biggest pain in the butts ever, but you know that as well as I do at this point. Unless you wanna sit under there for a couple hours at a time which turn into days and many profanities churning from your mouth go and buy a MAPP torch. It burns hotter than a propane torch but looks almost the same. I am almost positive they sell them at Home Depot/Lowes. Now from this point you will sit there and heat the bolt up. Now watch here, first the rubber is going to catch on fire and it burns really well. Have a fire extinguiser handy. Second the actual bolt that goes through the spring actually has a cylinder that houses it. This cylinder is even harder than the bolt to cut through. So back to the point, heat up the entire assembly and then have a big hammer and something to drive that bolt through the cylinder and through the frame. Obviously you will have taken off the nut at the other end to do this. Eventually after hitting it enough and using rage as a second wind you will have driven the bolt through.
This is my advice, by no means is this a simple job, but it made my experience much easier. I had used the sawzall first but only got through one side of one bolt which actually made it harder to cut the other one since it was leaning against the side that was still attached. I think you can pick up one of the MAPP torches for less than $30. Any questions just let me know. Good luck!!
