    1974 27' masthead sheaves and pins size

    Having the jib halyard jam in the masthead of my 1974 27' this past autumn while prepping for the long winter that we just survived in Michigan, it is now time to face likely repairs to the sheave and possibly the halyard too. Does anyone out there know the dimensions of the sheaves and pins in the masthead? Both will be replaced on the main and jib as a proactive measure. Could you recommend a good source for the parts?
    Thank You.

    I have not needed any new sheaves... yet, but this guy seems to get very good reviews. You do need the accurate sheave and pin size in place an order - no matter who the vendor might be. Is the mast down now?
