Hemi Motor Mount Bolts?

[SSing]

What was the correct bolts used here?
And want the original look, so picture of early B-Body Street Hemi bolts, would be super also...
Would really appreciate this.
Thank you.

Fran Blacker, thank you.
I had an idea hardware may have been phosphate (spell) plated, but thank you.
