Stupid Question

Ok, two questions. I know I probably should know this but I figured I'd ask the collective! I have a 67 Dart GT and I'm upgrading to disc in the front using stuff from a 72 Demon. I want to put in all new lines from inline tube. Should I get the kit for a 67 dart or a 72 Demon? My car has 9" drums I'm swapping out everything in front: upper/lower arms, spindles, etc.
Also, I would like to upgrade to 10" drums in the back. How hard is it to do that and still keep my SBP?
