Form, Fit , Function
It would appear that after 18 years hot coolant will discolor plastic and make it hard to see thru. Well, quick search on good ol' Amazon and I found this. The product fits with no issue, the form is the same as the original and the function has improved as now I can see the coolant level thru the bottle

Good value
It's cheaper than Toyota part but needed a large washer to mount with the stock bolt. But it works OK and doesn't leak like my old one.
