Power brakes on a 67 GMC RETROFIT question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 67 GMC that will begin to work on soon.

I have plans to put in a Power Brake set up from a 71 Chyenne. Is there anyting special that I need to know about the set up?

I saw on line one time where a guy cut out part of the firewall with the booste and grafted it in the firewall too. Does this need to be done or will the Pedal assembly and booster fit?

I have not gotten rid of the cab at this point ot a point that I cant take this section if I need to?

Thanks,
Thomas

What is the benefit to doing this, i am going to put disk brakes on the front of the 67, figured the master cylinder i have would be enough??
