I don't think the BB-7000 is available in different widths, what difference would that make?
Tandem Tom, I'm new to bottom brackets but was just recently researching Mega-Exos. So I'm no pro but it seemed that in my reading there were some that were compatible with Shimano hollowtech II bottom brackets but it was hit and miss. I think the difference was the FSA aluminum road cranks were Shimano-compatible but carbon ones were not. Like the carbon ones were a fraction of a millimeter larger bore or something like that. However, the BB-7000 appears to be for their mountain cranks so I'm not sure. What crankset do you have ("Mega-Exo" is not the model of crankset but the style of the bottom bracket interface)?
