Info on dust caps for Wide Five hubs/drums

[Ziggster]

I recently purchased some wide five hubs / drums (front and rear) and I’m now looking for centre (dust) caps. I found a bunch of the threaded variety from various sources, but wanted to know if these look like the original
Ford versions. Also, regarding the front hubs/drums, one is threaded for the cap and the other is not. Could someone please explain why one is threaded and the other isn’t, and where I can find a non-threaded version? I did find these NOS threaded ones on eBay, but seller says they are 3” in diameter. What would they have been used on?
I should mention that is the rear wheel bolted to the front hub/drum just for a colour comparison pic I took.

The one for $9.95 is correct.

Most likely the drum that is not threaded is later Mfg. for an earlier year. The push on caps appear like the thread on without the thread. Not like the 7EQ you have shown.

Ok. Thanks for the info. Much appreciated.

The 7EQ-1139 (A8TZ-1131-A) Is for a 1948-52 F7, F8.
7EQ-1139 is from a 1948-50 parts book and A8TZ-1131-A is
from a 1948-56 parts book.

Geeze! Never even heard of an F7/8.

Think cabover and conventional semi and 30-foot trailer
