For reference, my GTO is a 64 hard top with front brakes converted to disc and rear drum.

First question is about rear brake lines. The picture attached shows my rear line ends short of the dual master cylinder and there's a frankenstein link that looks home made. Wondering if there is a rear brake line made by anyone that would go all the way to the MC.

Second question is about sourcing a bolt on dual diaphragm booster, I'm chasing hard pedal and my motor only generated 13-14. Is there anyone out there making a kit? I don't want to cobble something together.

Thanks

If you want a full length line from front too rear I would suggest Nicopp line by the roll and flare it yourself. I'm sure you know that the factory installed the lines on a bare chassis and without the body in the way it's much easier to install a full line front to rear.

If you want the brakes to work properly either a vacuum assist pump, an auxiliary vacuum reservoir, or hydroboost unit to combat the low vacuum.

Diesels have this problem, and have solved it with an auxiliary vacuum pump because they have no engine vacuum, or sidestepped the problem and assisted the brakes with a hydraulically assisted booster.
