I gave up. A friend drilled out the pins, we replaced them with standard clevis pins, and he notched the mast for me. He did something really nifty so that each pin didn't need its own notch. The box has to be inserted and removed at an angle, and slid around a bit in this process, but it minimized the number of cuts needed in the mast.

Ryan,

Thanks for your reply.

Here is a little tip: When I replaced my wire halyards with sampson spectron cored line I stripped off some of the cover of the line so I only had the 3/16 spectron line running over the sheaves in the masthead sheave block. I then spliced eyes in the covers that I had stripped off and use them for messengers to allow me to pull the bare spectron back inside the mast when I am not sailing. Since I used different colors for each of the halyards the covers that I stripped off match the covered part of the halyards and my messengers are color cordinated - making it much easier to identify them. I also used luggage tag splices on the end of the halyards so I can replace the shackles if neccessar without having to resplice the line.
