I agree. I bought all the components, and a good friend and I plumbed the whole car. The hardest part, was getting the coiled tubing straight enough for my anal brain. Strange put the axle vent on the right side tube, so I had to move everything over to that side. The plumbing from the master goes into the interior for the prop-valve and Line-lock. I also always run the front cross-over line in the interior.
