1951 1/2 ton vs 3/4 ton Rear axle shafts

[pwrwgn]

I have a 1951 B3C that I am restoring and a 1951 B3B that I am using for parts. One of the axle shafts on the B3C is damaged and I am wondering if anyone knows if the shafts in the B3B are identical? I am guessing they might be as it seems both take the same axle bearing and axle inner and outer seals, but reaching out to see if someone can confirm before I go through the effort of pulling the B3B axle apart... Thanks in advance for any wisdom here.

If I am looking at the parts book correctly, yes they should be the same.

 

 

Hollanders seems to agree.

One more related question Bill, that perhaps your book will answer if you dont mind? It looks to me as though rear axle drum/hub, brakes, backing plate are identical between B3B and B3C 1951... It looks to me as though front axle B3B has 10"drum/hub and associated backing plate while front axle B3C has a 11"drum/hub and associated backing plate, while front axle spindles on the B3B and B3C are identical. Can you confirm this in your books or do you find different? Thank you inn advance for any additional help!

That does appear to be correct the Front 1/2T is different than the 3/4 and 1T (book does not specify size)

The Rear is also different between each 1/2, 3/4, 1T and L and R on the 1/2 and 3/4T

The steering knuckle (spindle) also appears to be different for each 1/2, 3/4, 1T

On a '54 the brake drums are different between the B Series and C Series.  The B series has a 5 x 4.5 bolt pattern, not sure on drum size.  The C Series has a 5 x 5 bolt pattern with a 11' drum.

Sure would be nice to find some new 1951 B3C hub drums! I see B3B available, but not for the C (bolt pattern). I guess I could take apart a new set of the 11" B drum hubs and mate my B3C hubs to the new drums, but lots of $ to do that...
