"S.O. Number"
"S.O. Number"
I can't find anything that says what the S.O. No. field on the data plate represents. Any ideas?

Re: "S.O. Number"
S.O. stands for shipping order.
I looked at all the 1968 trucks in the registry and over 90% shown have an SO number that begins with 17 or 18. There are a handful that begin with other numbers like 2,4,6,7 and maybe 9 (I forgot already
), but all have a 7 or 8 as the second number.

SO stands for "Sales Order" as u in 2013 and Ben in 2008 stated in the posts linked below:

Re: "S.O. Number"
That is what I thought, but author James Schild refers to them as Shipping Order numbers in his books. It looks like he is wrong going by Ben's picture unless cars had it listed differently.PwrWgnDrvr wrote:Bill, CRS gets worse as u get older.soopernaut wrote:S.O. stands for shipping order.
