I love my OEM 18 wheels on my 06 LX470 wheels (in their original finish)

( I rarely see them posted in the classifieds but occasionally they to pop up)
A quick Internet search found these

A neighbor has LC200 (5 spoke) wheels on his 100 series and they're fairly nice looking (but not quite as nice as what should've been on yours from the factory).
(I often see these pop up on mud classifieds and local craigslist ads)
May have to modify or find alternate hub caps to fit the caps over front hubs:
There are many more OEM LC200 and OEM Tundra wheels, that are the correct size/offset/lug pattern/bore size that are very commonly found on Internet classifieds for fairly cheap

People often have to work around hubcap issues with these wheels on the front hub.
Solutions I've seen wheel spacers, alternate 100 series hub caps, flattening grease caps, cutting holes in hub caps to allow grease caps to poke through, etc.
