You could do what 99% of car owners do. 
That's probably more of a concern. But there's enough of those around that I can't see it costing a fortune to swap the rear... right? 
He's not wearing pajamas while driving, this automatically triples his IQ (as a minimum).
Unless he visits Z-guy who has 10 Z cars sitting in his front yard in various states of decay, he's looking at close to/over 1000 dollars for a remanned diff, since it seems the R200 is a clutch-type LSD. I'd be v hesitant buying a junkyard diff from ebay, maybe local pull-a-parts have something that can be used.
I'm dumb, Datsun 280zx's in the US didn't come stock with an LSD, but it was an option, so who knows what the gently caress you got in the back of it. OBX (ebay chinese knockoff poo poo) probably has an aftermarket helical LSD that will work in it though.
I see some rebuild kits with bearings and gaskets for ~$4-500. 
I'd ride on it until it became really sketchy, you just put oil in it, so it *should* be ok for a decent while yet. (I accept no responsibility if it explodes and sends you into a ditch)

300ZX 87-89 Turbo MT and A/T (3.7 ) (R200)
Note Turbos:
#1) after 4/87 only-(3.7 Clutch Type LSD)
2) 88 All White SS used a 3.7 Viscous Coupling LSD)
3) LSD Unites Came With Finned Rear Covers
Additional Comments: a) Viscous Coupling LSD requires special splined half shafts - b) 84-87 R200's can be used in earlier cars, but require modifications they are not direct bolt in swapable to 240/260/280Z/280ZX's c) 84-89 R200's used a 12mm bolt in the ring gear - earlier R200 used a 10mm bolt in the ring gear, so you can not swap Gear Sets with the older R200's
Some more stuff I fished up regarding rear diffs for Z cars.

Ignore my post about diffs exploding and making you wreck, that can happen with a 4wd locking diff system, I rode through what happens when the front diff in a jeep grenades while moving, and it is not fun. LSDs just go POP and grind and you wheel it over to the side of the road and call a tow truck.
That's not fun either though because once they go, you will be looking at buying a whole new diff instead of just replacing the bearings and changing the oil.
Also, easy way to check for LSD on a 280ZX, a finned rear cover. If not, it's not an LSD and won't be as bad to work on, if it does, god be with you.
