Both bolts are 5/16-18 coarse thread. The adjuster bolt is 1" long from under the head. (The correct way to measure )
That’s a good one. Also how about the little screws that hold the positive battery cable tray to the block!

This? I have more of these. They also used this single bolt at the top of some differentials,like the 12-bolt Chevy,to hold the brake hose bracket on. The other 11 bolts were shorter,with an integrated washer. I will find more. This one is not that nice. I have a bunch of those TR bolts above.
Brian, I was able to find what has been deemed as two different but correct (thanks to this thread) bolts. Thank you for looking.
