Generally speaking part numbers between Lexus and Toyota are interchangeable. Most Lexus parts counters will match prices in some way, some can't match enough to make it worthwhile. Some Toyota dealers will have parts by number, I usually tell them it's for a 4Runner or FJ Cruiser–whatever it could have been on originally. There have been experiences where a Toyota dealer wouldn't sell a part they knew was for a Lexus, but we've only had a few reports of that.

For small OE parts, Partsouq is a great resource in Dubai. The parts are inexpensive and shipping is fast. Try there if you need something small, obscure or for parts from a Land Cruiser Prado. They also publish parts diagrams so you can see what you're getting. For Toyota-crossed parts, Camelback Toyota in Phoenix, AZ is a great resource in the US. Their prices are really good and shipping is relatively reasonable.

Also check Amazon.com. They often have OEM parts with Prime shipping. Searching by part number is the best way to find what you need.
