Rogerdodge:
It should be available under Window > Toolbars > MEP Toolbar. If it is not there, try going to Work Environment > Command Layout Schemes > and select
MEP Commands 19 (or MEP Commands 18 if you are still on AC 18 ), apply it, and the toolbar should appear as an option. This will change your current Command Layout Scheme in your Work Environment. Unfortunately you cannot import just a Toolbar. You could also create your own Toolbar using the MEP commands.
