Anyone have a good method to remove the upper outer bolts that hold the Rear Lid Spring Assemblies to the underside of the rear deck? When I tried to remove #4 body mount bolt, the captive nut inside the body turned. Thought I would take out spring assembly to get at top of #4 bolt and bead blast spring assy at same time. The factory must have had an access hole in the back of the spring pocket to install the bolts. I can't get enough wrench motion to remove the bolt. Any suggestions would be greatly appreciated.
