I’m finally getting around to installing some extended brake lines in preparation for a 4” lift. Based on various threads I ordered 3 OEM brake lines (pic 1) originally equipped on a tundra. I crawled under my rig but I can only identify 2 lines that need to be extended - a line on the front passenger side (pic 2) and a line just over the center rear diff (pic 3). I thought there was another in the rear that needed extending. Which one am I missing?
