I have a clean 95-00, Black Leather Complete interior out of a 99' LS400 for sale listed here if anyone is looking https://www.clublexus.com/forums/market/975499. Seats, door panels, dash and carpet will fit in 95-97 but may need some connector changes to make the electric seats work vs. plug and play in 98-00 models. Located in Chandler, AZ.

 

Visited your link. Am using a black 1999 driver's seat in near perfect condition while my cypress seat is being fitted with new covers. Unclear if your set has heating elements...

 

Yes, my interior does have heated seats. I also have the console mounted switches on the wood trim piece. Tested both seats for all power functions including headrests and everything functions. This car also came with the NAV setup, that I also have. Approximately 151k on the chassis.

 

Please refer to the Marketplace listing rather than discussion here.
