Yes, I did pull the gas tank but, it was out already. I think if you drain the tank and fill it with water you will be good to go. Let it air out. Leave the gas cap off. I once welded my gas tank after first filling it with water. It was out of the car. Do you have a shut off petcock at your tank? If you don't they are easy to install. I used a radiator pet cock. Also used a fan to blow any fumes and smoke out from under the car. It's a pain, but to be safest, I guess you should remove the tank. But, since it's the pass side, I think you are safe. Removing the two backing plate/radius rod bolts will also work. It's just more work to reinstall them than the front bolt. I think you are well on your way to solving your problem. I never knew the SW spring was such a monster. Hope your bushing aren't chewed up. You will be surprised how easily that spring perch will bend using the rod for leverage. Let it cool in the open air. NO WATER or air hose. Good luck.
