It's a 3.54 ratio for the std. 131" WB C49 Imperial 4 dr. ...same as a 1950  NewYorker and Saratoga with the Prest-O-Matic transmission and FD.

The Crown Imperial...too rare to discuss.

I don't think you will find a pumpkin tha fits the housing in a ratio that high.   time to measure the old unit and go salvage shopping for a complete rear axle.


What engine and trans are you running that requires such a ratio?  Just curious.

Might be easier and maybe cheaper (only if you can find used) to change the trans to an OD.  Maybe a 200-4r as they are smaller and more efficient that the 400.


But the 3.54 isn't bad.   That was my goto ratio back when I really like brisk acceleration but needed to drive it to work too.
