The DD pack should be up on my site now under 'Programs, etc.'
It includes three folders - the Fed DD, Klingon F5, and Romulan KF5R (FEDD, KDD, RKDD, IIRC).
Anyway, in the F5 and Romulan folder, there is two versions of the L9 mesh - one with the warp engines swung 'out' FASA-style, the other with the engines swung 'in', as picture above, like the rest of the Klingon fleet does. Also in each folder is a tripple warp engine variant for the F6.
