My expansion tank developed a slight crack, letting out some steam at high temps.

Went into Ford, gave the right model and year, found said item on MicroCat, double checked model and ordered.

It turned up today, looked great.

Tried to fit it and its a good inch taller, the screw holes dont line up and its got a funny "hollow" on the bottom.

Basically, its carp

Anyone had similar probs, is the right one still available?
