Anyone know, for sure, what year they changed to the larger steering U-joints?? ('73, I think???)
I have a '70 front end (with discs) and it has the smaller 1.0625 cap u-joints. The later model D44 I have has 1.1875" caps on the joints.
I checked an online parts supplier, but they listed the same joint for everything, and Im sure thats not right...
I would suggest that anyone swapping an axle steer clear of the early, small joint versions...
some prefer the 10 bolt over the small joint D44s
However, these early axles also seem to have the correct knuckles for the crossover steering setup...
I think you can swap knuckles??
