Power Brake booster hose location?

What sort of problems are you having with your power brakes? My mom wants me to add power brakes to the 69 Charger... She hurt her ACL a few years back and using manual brakes just isnt something she finds enjoyable at this point in life.
Firstly, All of the "direct fit" Lines are NOT direct fit....wrong thread pitch fittings for master cylinder....then had to cut the ends off and have new ones flared, then those leaked everywhere, also couldnt find anyone who made lines for DISCS in the rear so had to cut and modify again to try to get drum ones to work, both of those leaking fluid too due to the stainless lines not taking a flare worth a damn. I wish i would have left it manual front, drum rear and just full sent it with a classic industries oem line kit and been done with it. Also, with the added bulk of the booster, it makes working in the driver side of engine bay a real pain in the rear. I just dont know that the bennefit of power brakes is going to be worth all the extra hassle and hidden costs. To be determined once its drivable, but i know my dart had NO issues stopping under duress. Zanesville people love to run stopsigns and redlights and pull out in front of you then slam on the brakes when they see you to make sure you T bone their ***...
