Motor plate & mid plate... any photos?

Is anyone running a B/RB motor with front and mid plates in a 67 or later A body? If so, who made them? I see Mancini and Competition Engineering both have something for this application. Curious on fitment and potential issues with timing cover, etc. How was the installation? How bad are the vibrations? The last plated motor I car I had wasn't much fun on the street.
I'd like to see a photo or two if possible... and thanks!
