Man, it was not cheap, but my gearbox was a disaster. Prior "builder" literally installed parts backwards. CMS was surprised the transmission operated as well as it did. 1-3 gears were trashed, needed all new bearings, ring and pinion was shot, needed all new sycnchros (except reverse), needed new oil pump (debris had run through it during a prior "incident," and lots and lots of other misc. parts. If the part was worn or marginal, it got replaced. I also upgraded to a billet plate of some sort that performs better than the oem part (which can wear and allow the pinion to move around and cause wear), and a "shift arrestor" part that allows the gears to engage deeper. Total cost (not including the 3.89 ring and pinion from the 7.2rs which I had previously sourced before i knew the entire box needed to be re-done) was just a hair under $15,000 (sigh!).

What am I looking at paying ballpark if I have a local shop pull the diff and send it off to a Guard reseller? Probably don't want anything exotic just want the diff back to good working order.

$2k for LSD rebuild roughly. See link.
The removal and reinstall is the bigger labor question.
replace carrier bearings, reshim, drop transmission? $3k easy or more.
Remove and reinstall LSD only hoping carrier bearings ok (like DIY link above) with shop that knows how to do this?
$1k
Just like there are ways to pin coolant lines without dropping engine, there are ways to replace the LSD without dropping transmission. But not every shop is familiar. And in some cases it is better to do the whole kit and kaboodle
