D.S.O.

On Grandpa's '65 F250 4X4, NummberDummy told me to look at the D.S.O. code to see if it had 6 digits (it has 5 overload springs on each side). I just looked the other day and it is empty. It has NO D.S.O. code. Why?

No Domestic Special Order, the DSO code is two digits. FoMoCo peeps did not always stamp the code in the correct location, so...

It may be stamped further to the left near RPM
