I again apologize in advance for what to many on this board must seem like some of the silliest and dumbest questions ever asked. If there was an award for dumbness, I would get it

I want to install a bronze cleat on the aft deck port side to match the factory installed bronze cleat that is on the aft deck starboard side. I plan to drill 4 holes for the cleat and use Starboard or similar as a backing plate.
Question 1: Is the aft deck balsa cored

Question 2: I measured the size of the bronze cleat on the starboard side and came up with 6 1/2" tip of horn to tip of horn. I went to Spartan's website and could find 6" and 7" cleats but no bronze cleat that is 6 1/2". Does anyone know the correct part number for this cleat to match the cleat on the starboard side

Question 3: I am going to replace the winch handle holder that is presently screwed into the exterior port side bulkhead. Is this bulkhead also balsa cored or is it pure fiberglass


Thanks in advance for all of your continuing assistance and support and again, my apologies for continuing to ask so many unquestionably dumb, silly questions.
BTW, tried to go sailing today using the large Genoa for the first time. Although it looked like rain, I decided to go anyways. As I was getting ready to hank on the Genoa while still on the mooring, there were two huge lightning bolts followed very shortly by loud thunder. I decided to surrender to Mother Nature and staged a timely "tactical retreat" to the safety of the sailing clubhouse. A driving and blinding rain came across the Bay moments later. There was also rumor of a water spout but not sure of its accuracy.
