I am sure someone here knows the final drive ratio for the differential in my 1939 La Salle Coupe...I believe it is a 52 Series

Thanks

According to my 1935-55 parts book the differential ratio in a 39 Lasalle is 3.77 to 1.

Your LaSalle originally came with a 3.92 ratio. They stopped selling the 3.92 around 1941 & show only 3.77 as a replacement in the MPB  after that.
