Help me improve my brakes

I'm happy to report success!! I installed a replacement booster and, now, the car stops!! I had to replace the push rod linkage between the brake pedal and the booster. I never want to do that, again. I'm 79 and not as bendable as I used to be. I removed the driver's bucket and laid on the car floor on my back working on that linkage for hours. BTW, for those who have never done it, the shoulder bolt and nut are are center and above the steering column - pretty much no see, no touch!!

I want to thank everyone for your tips and support!!
