spark plug wire plastic holders- 1965???

I know I've seen them listed somewhere, but can't remember where. I'll bang my head against the wall & maybe something will fall out.


Found it!

Wonder what my NOS set is worth? I could probably sell them on ebay & buy a set of the repops. The reproductions are probably better material than the originals too.
