64 front hubs?

[John F.]

Are these 64 original or replacement hubs? I have never seen one with markings in millimeters.

These are not hubs; they are brake drums. As far as I know, originals did not have max diameter embossments in millimeters

My error Joe, I knew they were drums.

Re: 64 front hubs?

Original drums did not have the max OD die stamped or embedded in the casting. This did not become a FMVSS until 1/1/68. IIRC the max diameter was either 11.090" or 11.060" on later drums, and I recall some were die stamped until the tooling was changed to embed the max OD in the castings.

280.9mm/25.4 = 11.059"

These drums are likely "modern" aftermarket replacements cast oversees.
