273 V8 spark wire routing, looms and grommets

As I recall, other than the spot welded tabs on the valve covers, the only wire separators were one 4-wire circular type free-floating black plastic separator on each side between the valve cover tabs and the distributor. You can barely make one out in my old pic, just above the oil breather cap. I've still got a pair or more somewhere in my stash, but was unable to find them when I looked just now. Pretty much, you just run the wires however looks the neatest, and without too much length (like so many aftermarket wire sets).
