Will the Northbridge & Southbridge heatsinks from the E768 fit on the E758?

I very much doubt it, if i recall the 758 came out first and the 768 was the ftw3, if you look at images of both you can see the esata port on the 758 and the 768 does not have that. Even some the classified boards were like that, you would think one heatsink would carry over from one to the next but nope. Its still that way now.
