For 1965 (Pontiac) the build manifest gives the handy decode on the document itself.

I did a quick cursory check and many of the codes seem to be the same for 1964 and 1965, so this might get you started.

The codes are read using the box number and then the specific option content, ie:

Box 38 code 2 = GTO
Box 39 code 8 = manual antenna

If the number is higher than any of the individual choices it means they have been combined (they add up),ie:
Box 42 code 7 would be W/S Washer (1) + Dual Exh Ext (2) + Inst Panel Pad (4) = 1 + 2 + 4 = 7

etc

Your best bet would be to find this book:



Unfortunately, that could prove difficult since Eric has passed away and the book is no longer in print. They very very rarely come up for sale new.

In view of that I'm going to go ahead and post the sales code listings, as well as their UPC/RPO counterparts and pricing. Eric had previously given me his permission to use his information as I see fit, so I am going to deem this OK in this instance.
