273 V8 spark wire routing, looms and grommets

I just looked in the 67 FSM in the front of the engine section.

Many of the images are reused from prior years.

It clearly shows the drivers side has round split retainers on the valve cover and the 4 square intermediate retainer.

It also shows the passanger side as having the round split retainers. IF the image is factory correct for A year, it might be correct for the first year that the image shows up in a FSM
