I talked to Aaron and toyota. Aaron says they are special order from japan and can't help with that, the local toyota store says the numbers I gave them are good but have never ordered them. Im trying to get the oil gaskets, turbo to exhaust, water and elbow gaskets. From all the posts ive read about going single nobody mentioned about doing it because of the gaskets lol. I can cut my own oil and water gaskets if I have to but the exhaust have to be original.
