rear differential

blondwookie

In my 48 Coupe, i reinstalled the correct rear end for my car. I have the removable carrier , like the Chrysler 8 and 3-4 and the ford 9 inch. Is there any ring and pinions for this system, that are possibly new? I do believe that mine is 4.59, for  my overdrive transmission.

There certainly might be some NOS gear sets out there (would 4.11 have been the standard, non-OD ratio?).  I'd e-mail some of the "regular" Hudson vendors who advertise in the WTN to see if they have any.

The other possibility is to replace the original, Hudson-built rear axle with the 1952-and-newer Dana rearend.  I believe it would have the same wingspan as the original one.  And I'm told that a number of different ratios are available, since this same rearend was used in a number of car makes.  Here is a discussion of Danas:  https://openforum.hetclub.org/discussion/170599/looking-for-a-dana-rear-end://

Can someone please tell me where I need to look on my rear carrier to locate the ratio of my differential

You can always do the ol' spin the tire count the drive shaft revolutions. Here is a quick how to. I'm sure there are several other websites with more details.
