baer brake install HELP

[dougs68ss]

ive just put on new baer system, the kit came with a new master cyl, but the line outputs from the m/cyl (front rear) are opposite of what i have now. they say to swap the lines over to match theres, but what do ido about the rest of the underhood brake parts? (factory porportioning valve ,monitoring valve etc) do ihave to reroute these too? or can i just keep my original m/c in place (its new and looks identical to the baer) my car is a factory power disc SS car drums in rear.... thanks ....doug
