Oh, and BTW - I got the Carter WA-1 designation from this site which I took to be 'gospel'
https://packardinfo.com/xoops/html/modules/modelinfo/viewmodel.php?model=929 I have never heard any reference to Chandler Grove in my 38/39 manual, so while that may have been the model-correct carb for '37, I don't think it applied to my '39. I have seen quite a few photos now of '39's and most seem to have the Carter WA-1.
Like I said initially in this post, I had a '56 Chev Bel Air carb on it when purchased, and all research I have done has indicated that Carter was the overwhelming choice used by Packard on my car. When I gave the carb X-change outfit my make and model, that's what they listed.
