Mike;
Welcome to the Forum. It might be that a custom cabinet shop will be your best bet since not all these table top dimensions are exactly the same  size. Let me share with you a quick story. Since there are usually only two of us cruising, I decided to eliminate the large table in the salon and use the gaming table for dining. Then a friend, who had a C-36 hull number only nine hulls away from mine - gave me his Catalina factory table top. It turns out that his factory supplied table top was an inch shorter than my original one. This became obvious when the salon table top was made into a berth.  That indicated (to me) that not all of the wood parts are exactly the same size. You might want to talk to a custom shop.
Good Luck,
Bill
