So I have gathered up my parts to convert my brakes from power to manual. I have a master cylinder, firewall bracket and push rod. What I can't figure out looking at the parts is, how does this stuff connect to the firewall? Is there already bolts in the firewall that I mount this stuff to, or do I have to buy the bolts? I haven't taken the power brake booster off yet so I'm not sure about this. I just don't want to take it apart until I have all the parts to put the manaul stuff on. Oh, forgot to mention this is on a 70 Cuda.
