Good pedal til car is running

Thanks for all the advice guys, i just haven t had time to mess with it yet. The master is for a 73 power brake car. The booster is a reman 73 unit. So i m guessing the rod in the booster would be the correct one. But there is obviously something wrong so thanks for all advice. I wish i had a 73 manual book. I have 71 and 72 but they re pretty useless since its a completely different system
