AXLE 29 = Dana 70 / 5.87-1 / 7,400 lbs. Rear Axle Capacity.

Some 1961/62 F350's have Timken B140 rear axles, some have Dana 70 rear axles.

ALL 1963/84 F350's have Dana 70 rear axles except 1979 F350 4WD that have Dana 60's front & rear.

No F350 of any year came w/a Rockwell rear axle.

 

It's hard to say what has changed in the last 50+ years. The warranty tag describes a 1963 F350 equipped with the standard Dana 70. Could be sheet metal moved to an older chassis/drive line or the axle was switched. If the tag in post #7 was removed from the rear axle of the truck in which the warranty tag was posted then the OP should refer to that axle as a Timken axle not a Rockwell. The stylized "TDA" triangle is Timken Detroit Axle the tag is clearly stamped B140 this series axle would be correct for a 61-62 (probably back same back through the 50's).

 

Sweet looking truck. It almost looks like my dream truck...

 

Whats the tire size?

 

"poppatello" can you offer any details on the blue F350 photo you provided?
Where can that truck info be found, if there is a thread within this forum?
Thank you.

And good luck with the 'subject vehicle' mechanical restoration, topic of this thread, and please provide more photos.
