Here are pictures of my 67 with the 8-bolt water pump, but I think the timing cover bolts are the same for 67-69.
From top to bottom: 1 skinny bolt with "bat wing" washer at the very top - goes to the intake manifold 2 studs - the one on the pass side has a thick ring and the engine hook 2 bolts just under the water pump 2 bolts at the bottom 4 bolts through the oil pan (not visible)
