The NCRS Tech Manuals and Judging Guides are just that....Judging Guides. I've been involved on several occasions with the rewrites of the 63-4 Manual, the 68-9 Manual, and the 53-55 Manual. Frankly there's just TOO much information to put everything in any one manual. If you tried, they would look like hard bound books.
The ECL code info is available in Noland's book and now in Al Grennig's book. Judges and owners of those years become knowledgeable about the codes that apply to their areas of interest.
Many have asked questions in the past such as why aren't ALL bolt head markings for every application listed, etc.
You could write an entire book on the 67 and it probably still wouldn't contain all the info available. SO....you've got to be your own "judge" and use many sources, the NCRS TM and JG's as one reference. Chuck
