[1968_K20_4x4]

Ok so I think I am leaning towards replacing the front axle with a newer Dana 44 with open knuckle, disk brakes etc. Ill keep my original axle in the truck untill I can find a suitable replacement. So now the big question is specifically what axle to be looking for? I definitely would like to keep a Dana 44 and not go with the 10 bolt, to me the Dana just looks right under the truck. Also I want to reuse my power lok unit as well. Another thing I would like to retain is my "Selectro" locking hubs that I currently have on the truck. So does this mean I should be looking for a "big hub" axle? What are the differences between the "big hub" and small hub axle? Is one better than the other?? I found some info from a site called Torque King 4x4 that I will post below that maybe someone can confirm:

The Dana 44 was the sole front drive axle used in by GM from 1973 to 1976 for SUVs, 1/2 ton and 3/4 ton 4x4 vehicles. In 1977 GM started to replace the Dana 44 with the all new corporate, 10 Bolt, 8-1/2" Ring Gear, beam type solid 4x4 front drive axle, however, the Dana 44 continued to be used by GM to the 1980 model year after which it was dropped entirely from the GM lineup. For the Dana 44, 1977-1/2 also marked a change in the hub and spindle design for all models. Although the differential parts are totally different, the 1977 to 1980 GM Dana 44 and the GM 10 Bolt front axles share a lot of common parts from the axle u-joints out to the hubs.

I have a potential lead on an axle locally which appears to be what Im looking for. It is even my proper gear ratio! But I just want to know exactly what I need before I go out and buy something. The guy says it came out of an 80s Chevy.


Once again thanks everyone for all the great info!! Im sure I will be needing lots more advice as I go along
