What are the differences besides gear ratios, SRW/DRW, drive flanges/selectable/auto hubs, fat/skinny shafts?
Were the first 2 years different?

1977-78 vs. 1979-91 Dana 60 front axles
- Thread starter GreenieK30
- Start date
The early years had neck down inner shafts and 6 pin hub socket for the spindle nuts. Iirc 77-79 models.
Early years had narrower spring perches. They match the GM trucks. Later axles had a wider perch like 36" or so.
I believe the OP is asking about GM version D60's, whereas, Wes is talking about Ford axles.
GM, correct 
and first 1 mabye 2 years had cast iron pass side dust cap over all the rest tin cap.
and i have one still on the axle with 37,xxx miles on it.
better chances of finding factroy drive slugs also on the 60 from 20 full time 4x4 cases used a lot.

Yep, once again I got ahead of myself reading the post too fast and replying right away instead of taking time to read each word slowly.
I just discovered that early 1977 bearing hubs dont have the big outer groove for the driveflange/hub snapring. But the later 77/78s have it
mine is a 78 srw D60, its got a grease nipple for the wheel bearings on the hub hidden up buy the wheel studs. Ive yet to see another one like it? Its cast in a bit so its def. factory.
you can see it on the upper left part of the hub.
