I have had this for decades. Time to go.
First $25 (+the ride) gets it.

Do you know what size this is? I'm interested in it for my early 454.

The metal part with the "O" ring is 1.445
The OD of the "O" ring is 1.64"
It has to fit a 1.5" soft plug.

Thank you for checking. I checked my freeze plug and it's 1.75" so it won't fit.

Great NOS part, good luck with the sale.
