I used a 7" booster from a 1987 Mustang. The m/c is from 1978 Camaro for disk/drum setup, but disk/disk m/cs are about the same physical size. Used the stock pedal and pivot. As mentioned above, the whole unit sits further back from the stock location so I needed a new access hole in the cab floor; it's now close to the seat support. The combination valve mounts in the usual place on a L shaped bracket under the m/c.
The booster allows you to use a larger diameter m/c which reduces brake travel. (I am using 1 1/8" dia bore Raybestos MC36306)
I have a Camaro rear axle with drum brakes and Camaro disk brakes on the front. Had to do a panic stop last summer; I was impressed how well the brakes worked.
