Ah, but you know something...Toyota parts that have a color to them, like this emblem, often have an incomplete part number molded in; different color parts may use the same die or mold, so they'll show the same part number, but it ain't quite the whole story. I don't know what color cars got white lettering, but check this page out:

I suspect 75471-17070 is the chrome one. I just don't have enough MkII experience to say for sure.
