    That's the most common configuration for a shackle, or clevis. I'd say 
80-90 of them are like that.

    Sure - that's fine. Mostly the hole in the pin is wired to prevent 
dropping the pin somewhere along the line. With typical guy tension of 400 pounds 
minimum, the shackle pin isn't going anywhere so there's really no need to 
safety wire it.
