Consider using a torque multiplier. A "normal" amount of torque can be used without bending or over torquing extensions. It will also allow using a smaller, shorter torque wrench which give a better swing radius. Using the one in the link below, I would place it in the bildge and "frame" it in place with wood. They are usually 5:1 so pulling 70ft/lbs should be a drastic improvement over pulling 350ft/lbs.
