If all you are after is 8 lug, just swap the caliper brackets, calipers, hubs & rotors. It should all bolt right on. The 8 lug may have bigger pistons in the calipers, so different hoses, and maybe a master cylinder, may be needed. I ran into this on an '80 K20 axle once.
If the ends will swap out, then I will just stuff em on, that will make things easy enough. From what I can tell they only offered a 4.10 and a 4.56 in 77, so it will probably be a 4.10. I think my blazer has 3.73's
