A 4wd 3/4 ton is a K/20. C/20 mean 2wd. If your truck is a '71 K/20 it should already have disc brakes on the front. I'm curious what you might actually have. As far as the 10-bolt axles used through the '91 V2500 (post-86 3/4t 4wd...ok,'87s were V20s) crewcabs and Suburbans goes,yes,it's a direct bolt-in

Special K sorry this the first chevy I have owned and currently I have it off of my property to surprise my son on his birthday so I thought it was a c 20 the guy I bought the truck from had told me the last time they did brakes they had trouble getting parts and they didn't work very well truck is also lower geared than I would like so my thought was to swap out for the most modern axles that would be a quick and easy

As Special-K mentioned, '71 should already have the front disk brakes which from my understanding are pretty much the same all the way up to '84ish when they went from the 7/16 banjo fittings to the 10mm. My assumption is that brake parts for the front axle are still plentiful.

The rear axle may be a different story though, depending on what it has in it. I know parts for the Eaton rear axles are getting harder and harder to find.

On mine, I replaced both axles because mine had 4-wheel drums and mismatched gear ratios. I found a front axle out of an '84 3/4 ton and the rear is a full floater out of a '91 crew cab. They are now both the 4:10 gearing, and other than moving the rear shock mounts on rear axle were a direct bolt in.

My son and I just finished his 71 K20, if you need any help or advice feel free to contact me, we are "just " over the pass. Parts for the front brakes are easy to come by, as was mentioned earlier, if you have the eaton rear end, they are a beast. We converted the eaton rear to disc brakes for the same price that it would have cost to rebuild the drums. You guys have a ton of options in this area. Good luck with the build and welcome to the forum.
