Spark plug wire grommets

[tcb-1]

getting ready to do a little under hood cleaning this weekend on my fairly recent aquistion (69 swb step). trying to locate the plastic spark plug wire grommets that were standard on the ls9 350. they mounted to a metal support.

does anyone make these? trying to keep under the hood bone stock and factory. here's a pic of the grommet on the passenger side, just to the side of the distributor. I still have one, but missing the rest. thanks guys.....
