Seems at least according to torque king the open knuckle 69 blazer is quite possibly a reality, which I’m not totally surprised about as I said before. I’m still not sold on the dials on non K/5’s pre ‘70. It’s been a while since I’ve played with the aluminum dials but I seem to remember that they don’t directly interchange with the plastic dial hubs. someone correct me if I’m wrong. It’s been a decade or more since I’ve messed with the spicer hub loks.
I’m not surprised on your blazer having blue dials from the factory either. I’ve seen other original later model year 70’s that had blue dials in the past.
