Is there anyone with a list of build plate S-codes and their meaning? I haven't had much luck getting anywhere with overseas or other local sources so far, but thought I'd have a go here.

I have these on my 74 144DL:

S-6167, 6261, 6263, 6264

Thanks

Beyond these from the 140 parts books, I don't know of any complete list.

This is from the 73-74 book. Some numbers carried over from the -72 parts book, where there are more.

Some of yours may pertain to your 'Californian' trim.
