All I can tell you is if it's a 3/4T, it's almost definitely an HO52. I believe HO72 came only on one-ton trucks. It's been discussed before, and if I'm wrong, someone will be happy to point it out.

As to the load bolt, all HO72s had them, and some HO52s had them but some did not. My '72 K20 has an HO52 with a load bolt.
