Im convinced there is so much bullshit with these companies Right stuff is a joke

Looks good. Since yours was a drum-drum car, the factory block is just a "distribution block" with a pressure imbalance warning switch (to dash lamp, in parallel w/ hand brake switch). For anyone with a factory disk-drum car, you wouldn't want to keep that different "combination block" since it has an internal proportioning valve which lowers pressure to the rear drums. The added adjustable proportioning valve is mandatory if adding front disks and keeping rear drums, to reduce drum pressure to avoid locking up the rears first. In your case, it wouldn't be needed if front and rear disk brakes are equally matched, so might need it set to just slightly reduce rear pressure. Ideally, test the brakes in a wet parking lot, with a ground observer. Adjust until the fronts skid just before the rears.
