273 V8 spark wire routing, looms and grommets

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 !

The double one piece ones are for 67 and newer. The 64-66 takes the individual ones. Now, in 55 years a valve cover could have been switched out. like Dana in post #7 mentioned above.
