Masthead Block

[Ryan]

The masthead on my boat does not use built in sheaves, but instead uses blocks attached to holes in the masthead (shown in the photo). Have you guys got any suggestions for blocks? I believe that Garhauer makes a toggle head block for the mast base that may work, but if anyone has setup a masthead like this before, I'd like to know which route you took.
