Power brakes acting silly!

kinda thinking about going to manual brakes. Can someone walk me threw the process. I know I need a manual master cylinder and the correct length push rod. I found out the parts store by my house has a adjustable universal push rod I could order. The thing I'm needing help with is the linkage for the pedal. Do I bolt the manual master cylinder to the bracket where the brake booster was mounted? Or do I remove that bracket drill a hole for the push rod to go threw the firewall and mount the manual master cylinder to the firewall? Could anyone post a photo of there conversion?
