You will need to modify the frame at the X member to fit a Packard R6,R9 or R11 to any pre 1939 Packard Six or Eight. You may be able to fit a 4.1 diff centre but the original 4.54 will simply overrev the engine if you try to keep up with traffic.
The 4.1 option would allow you to sit on 60 mph but anything over that will require an OD box.
I would suggest that any of the modern five or 6 speed boxes will only give you around a 15% overdrive, whereas the Packard OD's are a 28% overdrive
A 25% overdrive will reduce your 60 mph rpm's from around 3200 to 2400. If you already have the R11 you are nearly half way there and you can fit the 38 cane shift to the top of the box to make it appear authentic.
There is a bit of work involved but i have a 38 Six and 38 Eight with Packard od's and they work really well.
