The Cape Dory Board

Thanks: I should have been more specific in which exit block. I am looking for the jib exit block the upper one that is only for the jib.
The lower exit block is for the jib and the main halyard and it is part number SP911. Mike

I need to replace the jib halyard exit block on my Typhoon Weekender. Does anyone know the Rigrite part number? Is there other sources for parts?
Thanks,
Mike TY #1395
