What is the correct lug nut size (for removing the lug nut) for a 1955 T-bird, 3/4 or 13/16?

Welcome to Squarebirds.org, Franchi. Thanks for posting and I hope to see many more.
The Ford part number for your lug nuts is: C0AZ-1012-A
This is a 1/2"-20 nut with a 60° conical seat. Use a 13/16" hex wrench for removal. - Dave
