Only thing left on chassis before blasting is rear spring pins. Welded a nut to slide hammer adapter similar to shop manual tool. Neither budged and nut threads (fine) stripped. Help!

Should have mentioned it's a 57 3100. Pin can't be driven toward the chassis, and no room to get behind it to drive it out.
