Owner's Manual questions

[lasound]

Hi all! I found this in my father's garage, from researching on this forum, it appears (to my untrained eye) it is an original second printing? Is that correct? (From researching, hopefully I got it right, some tips are: The unfilled hole punches with "One" partially visible instead of 1.0 in the reproductions for the Stabilizer Bar - as well as the offset alignment of the end of fourth line of the paragraph on the cover) I can upload any photos you want, I took pictures of all the pages.

If so, my question is basically, when were the second editions printed? Were the first editions for the late '65 carryover cars? And the second printing a little later?

Just trying to understand what I have!
