Finding/Storing block position for later use?

[dmillerw]

Is it possible to find and store the X,Y, and Z position of a block when you place it, then store it to be used by an item?

 

I know there's onBlockPlaced, but I'm not sure how to find the block position when using that.

It's passed in in the arguments.

public ... onBlockPlaced(World par1World,...,int x, int y, int z){...

I think. But they're in the arguments. I know that much.
