I'm replacing all the running rigging
on my H38.
I ran into this when I went to do the boom vang
. It looks like the pin (is it called a bail?) on the block where the eye splice mates to it is permanent.
It almost looks like a rivet with one end the "factory head" and one end the "shop head" perhaps formed by pressing or screwing something down on it.
I gently tried to tap it out with a spacer and drift and got no joy.
