The nut I am talking about is the small 8mm or so head on the booster that the master cylinder pushrod sits on. I cant push the pedal and feel the master cylinder at the same time so ill have to wait on that one until I get a helper. Honestly I feel like the booster is already touching the pushrod in the master when its bolted up.

As for the valves all I have is the hard brake lines going into the correct prop valve as per CPP's hookup diagram. I verified that the prop valve is for a disc disc setup, they did not say to use any additional valves. Not sure what you are talking about as far as the depression in the MC but I uploaded a few pics here.
