Hello, I recently found one of the sheaves of my main sheet blocks is broken. I went looking to find a new block with the same mounting pattern but no luck.
Its looking like I'm going to need to drill some new mounting holes. Does anyone have any advice on how to do that safely?|

I am considering upgrading to a traveler system like in this post
But I want to avoid the big ugly plates and bolts if possible...
