brake/master cyl question

ok heres a stupid ass question , but i just want to make sure , im putting a dual m/c on my 55 chevy truck . Its in the stock location under the floor and faces the rear of the truck as opposed to facing forward like a firewall mounted unit . my question is the front brake line comes off of the port facing the rear and the rear would come off the one facing the front since its mounted backwards . right ? or does it even matter ? thanks

yes , it can matter..depends on your master cylinder and what brakes you are using ..drum/drum or disc/drum brakes?

 

oh yeah i guess i shoulda said , disc/disc , 77 corvette master cyl.
