No Whitworth threads on Packard automotive engines. Treaded fasteners on Packards, especially the prewar ones, were predominately NF with NC used more sparingly.

But it's unclear to me exactly what you're trying to separate from what, how about a better explanation or even a photo of what you're facing?
