Well I finally got those Dust Covers unscrewd. I bought a Multi-Purpose Strap Wrech Kit from Autozone. They have rubber belts to avoid marring the finish. I degreased the caps then heated them up with my heat gun. The first one popped fairly easy the second one required me to repeat the process a couple of times before it broke loose. The threads were dry, I will be using some anti-seize here for sure during reassembly. thanks again for the suggestions.
