66 Manual to Power Brake Upgrade questions

[buildinga55]

I am working on a 66 chevy C10 that has the original non power master cylinder. We have ordered a Stock Replacement Booster and Master Cylinder from OReilly that should be in soon. I know it would be best to put on a dual MC, but it is the father in laws truck and he does not want to. So here is my question. Do I need the angle bracket for the firewall to mount the booster or since it is a stock booster, will it mount to the firewall as is? Thanks

Thanks for the pictures, I did find your pictures on your site. Question. I am going from manual to power brakes. Where this Pin goes through the rod from the pedal to the master cylinder, is there some kind of lever there too? Some of the pictures look like there is some kind of support and lever system where the pin connects the master cylinder to the pedal pushrod?? Thanks
