Packard's 'Group numbers' and 'Part numbers???

Posted by Packard Newbie On 2018/2/27 20:24:45

Is there one parts book out there that has the picture explosions, part numbers AND the grouping system numbers in a single publication? I see the Packard Club sells a '1935-1941' Parts Book, (I'm looking for '39) but I don't know what's inside it.
When I look in 'our' archives, each category is listed separately.
Can somebody who has this figured out give me some help?? If I buy the '35-'41 book, is that all I'll need? Thanks in advance for any advice.
