I think I junked them, but wish I had a picture to share. The rocker shafts on my truck when I got it, were scarred and grooved VERY deeply. Now that someone has investigated the hardness, it’s remarkable to me they could get so bad.
I ended up replacing with some shafts off a spare engine that were in much better shape. And got the proper connector and rockers to make the late, pressurized shaft design work as intended. The rockers on the engine were a hodge podge of early and late design.
