Honestly I don’t know enough about it to help, I think the part number difference is the color. If you look on ebay you might get lucky. I tried using the PN at one of the online toyota sites and it calls it Mexico spec, It looks like I can order them brand new from toyota for 300.00 each.
He’s looking for these, its not true that ”all” 200‘s came with 18 inch wheels.
Several members of the 100 series forum have sourced these 17 inch wheels here in the US , I wish him luck 🍀
4261160640, 4261160660 part number
