Thank you very much for this information that you dug up. This will be very helpful in our search.

I started looking in the '35 - '41 Packard Parts Manual and found quite a few model numbers that had the same Ring & Pinion part number. I'm trying to convert all the different model numbers to model names.

The '38 Six 4.54:1 Ring & Pinion part number is supposed to be 900066. These are the model numbers I found that have the same Ring & Pinion part no.: 115C, 120C, 120CD, 120CA, 138CD, 120B, 120BA, 120, 1600, 1601-1D, 1700, 1701, 1703, 1705, 1801-T1900-1901, 1801-1901, 1803A-1903A, 1805-8-1905-8.

Now, all I have to do is find a NOS set, or a set in very good condition. I'm looking for maybe a 3.54:1 ratio.
