Re: 22nd and 23rd Series Suffix information

I agree there were probably some changes made by a particular dealer in California, and maybe a few others, but 95% will fall into the info I found. The main thing to remember is 22nd Series all start with prefix G, 23rd Series all start with prefix H. Suffix letters all fall after the end of the engine numbers hence the term suffix. According to the Packard International website. If the suffix (H ) was used by a dealer, it would be at the end (suffix) and stamped into the block. All factory hydraulic applications were only started by the Packard factory during the 23rd series, and had the Suffix (F).
