I am having issues finding the casting numbers on my '57 F-100. If they're where I have seen they're supposed to be I am not seeing it.

Possible replacements that have a different ID location?

I will take any advice I can get.

So far thos is the only number I have taken a clear pic of. Time for more brake cleaner I suppose.

6BN, not sure why it posted upside down.

Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

MoonShadow, 292 w/McCulloch, 28 Chrysler Roadster, 354 Hemi)
Manchester, New Hampshire

That is the casting date
There are three locations where the model could be
- at the same area you have in the photo but further along
- under the rockers
- under the intake runner

See here for some info and photos:
