Having done two axles I agree with him. Not simple or easy and the tooling is not cheap either. I will probably do it again but I need my head examined...
Find a used axle. If you have 6 lug wheels and don't have a large investment in tires and wheels... upgrade your LD 3/4 ton to HD 8 lug with a front (Dana 44 or 10 bolt) and a full floating rear off the same 75-87 K20. It'll be easier to mate the E-Brake cable from an 81-87. Whatever your axle year grab the entire E-Brake cable setup from your donor so you get all of the bits and bobs to make it fit.
You can sell your front axle to offset some or all of the cost of 16" tires and 8 lug wheels.
3/4 ton GM CK & RV Light trucks used 16" 8 lug on 6.5" bolt circle from 1967 to 2009. They will all bolt right up. You want to avoid split rims because most places won't service them and you don't want 16.5" tires because they are getting harder to find.
The only issue after that is matching the speedometer gear to the axle ratio and tire diameter.
