I owe you a response! I don't know really anything about Toyota's from that generation, especially Land Cruisers. That seems like it should be old enough to avoid the phone-home tracking systems. Likely new enough to still get parts for if needed. Take a look around at your favorite parts catalog website (Rock Auto here in states is good) and see if they have a good number of parts still available, ideally OEM from the manufacturer, aka "genuine parts" 

Also you may be able to use https://vehicleprivacyreport.com/ to see what it says. It might not have much from that era
