Did Ford ever stamp Ford on the pack nut? I've never seen one. Since he put Ford everywhere else, it seems logical he would have.
Limited experience with them, but also don't recall seeing one with script.
I've seen a round one and a hex one that is somewhat larger and thicker,but never saw a Ford script one.
Jack, where did you ever see a round pack nut?
It was on one of my aftermarket exhaust manifolds. I cleaned it up and screwed it back on,for the display. I guess they used a pipe wrench to tighten it back when,but this one doesn't have many marks on it.
