Thanks for the picture posting tip. It took me awhile to figure out how to get the image (as opposed to the link) posted.
It is a top-mount Tilton pedal box with triple MCs (front, rear, clutch) and mechanically adjustable front/rear bias. It's a nice setup in that it allows you to select a specific MC bore size for your application/preference. The MCs come with remote fluid reservoirs.
Mounting is pretty straightforward, but it requires cutting out one of the 3/4" tubes and welding in new mounting brackets.
