273 V8 spark wire routing, looms and grommets

67 commando 1 piece 2 wire snap in. Better pic of your tabs would help.
do the one piece two wire ones snap in? And are correct? There is a slot between the two saddles on the valve cover tabs.

so use the little snap on grommets or two wire single piece? The shop manual doesn't show it? Yea I know….damn purists !
