M_Boats: Mast Step and Compression Post Removal on Montgomery 17

I need to remove the hinged mast step mounted on deck and the below deck aluminum compression post on my 1985 Montgomery 17. I want to recaulk the stainless mast step and inspect the inside mounted aluminum compression post. Both are original installations. What is the easiest, best way to accomplish this. Best regards, Kirby Stross 1985 Montgomery 17
