Im convinced there is so much bullshit with these companies Right stuff is a joke

I have a 1971 Demon and did a 4 wheel disc power conversion setup from right stuff. They said everything was just bolt up which was partially bullshit. There is so many problems im ready to sell the car at this point with the amount of money i have invested. Disc kitswent on and bolted up no problem, but after that is where all the problems start. The power booster they sell comes with the wrong size petal bolt. Had to order a correct one. Next the brake line kit is a ******* mess. They have no diagram, instructions, or know how it is to be setup. I contact tech support they tell me there isnt any diagram. Ok so you sell a customized setup for conversion and no god damn instructions!? So i have them read where each bar code is labeled the best i get is rear or front. So i spend all day trying to figure out how the line are supposed to go and to me loose flexible lines not supported with a bracket seems sketchy. The front flexible lines dont go through the support brackets they are too big. Driver side hard line doesnt fit. And worsttttt of alllllll. The master cylinder lines they tell me that go to the original manual brakes distribution block have no scenario where they even come close. Every scenario has them pointing to the front, towards the hood or to the firewall. This is a complete mess i am at the point where im going to just undo everything to stock and loose thousands of dollars or sell it. How are people running rear disc kits did people not convert there lines and are using smaller drum brake lines? I dont get it because this setup pictured below seems sloppy.
