I'm looking for this website I saw before. I thought I bookmarked it, but I guess not.
It show graphics of how to install 3 different types of sheperds hooks in AK's.
I've got a romanian AK-47kit. The SH has a coil spring on it, and there seems to be an extra trigger/hammer pin. I suspect the 3rd pin is supposed to go through the pin somewhere?
I suppose I could just cut off the coil and install it like a normal SH.
Treasure hunt. In the Reference forum is a Big FAQ thread. Look half way down for the link.
