older d44s have smaller tubes, don't they? 2.75 vs 3", i think. i think 74 was the transition year.

This correct, however I think the transition year is later(around 1977).
Older Dana 44 have the 2.75" axle tubes.
Newer Dana 44 and 10 bolts have 3" axle tubes.
Be sure to use the correct spring plates also. The later spring plates have the holes spaced apart for the 3" inch tubes.
I have fought trying to put a later model Dana 44 with the wrong u-bolts and spring plates many times, and the work is much easier with the correct hardware.
