It is at the bottom of the link.
Option 1: Chevy parts: Grab a Chevy or Full Size Jeep Dana 44 knuckles and outer axle shaft. To convert these to 8 on 6.5" you'll need to find a 3/4 ton disk brakes Chevy truck (note some Chevy 1 tons ran a Dana 44 from 73-78). It can be running a Dana 44 (73-80) or a Chevy 10 Bolts (77-87) as these parts interchange! From the 3/4 ton truck you'll need the Spindle, Caliper mounting plate, Caliper, disk brake Rotor, Hub with lug nuts and lockout. Also grab the outer axle shaft, as all Chevy Dana 44's with the 5-297x style u-joint run the same outer shaft. Now you've the parts, make it work!! This option is harder to source parts.
Option 2: Run Ford 3/4 ton Knuckles Out, however you can only use Ford 3/4 ton brakes with Ford knuckles. This option will cost more, year for to source 3/4 ton Ford parts 76-79. Do note 76-77 is a larger hub and lock-out that is difficult to find. 77.5-79 runs the same lock-out as a 1/2 tons and is easier to find. See my Dana 44 article for more info between different types of Ford Dana 44 axles.
Option 3: Run Dodge or IHC 3/4 ton stuff. Here is how... Who am I kidding, I have no clue on Dodge stuff ;~) IHC see note in above.
Bearings, this is why you can swap:
Inner and Outer spindles bearing are the same part number for... as seen in the chart
