Id recommend getting the liquid bottle of liquid wrench, or else kroil, and getting a good amount of that penetrating fluid on the bolts where they mount to the LCA. Give them a little while (a few days of continuous application would be nice), some sharp pressure (hit them via a screwdriver, punch or similar) to help break up the bonds and help the fluid to flow... then be patient.
If they are bad beyond that, youll need t move towards more severe removal processes...
