    Large voltage Drop

    This is just the simple diagram of what I have set to the car right now. What I tried today: 1. I pulled starter and bench tested it, solenoid activated and held constant 12V. Obviously not under load so I will have it load tested this week at auto parts store. 2. I took the battery off of our...

    I doubt anyone has a set of these laying around but I need 1973 driverside+passenger side doors and would rather not pay 700 a pop to get them off Cj's. Anyone know anywhere I can find some of these?

    Floor Support Replacement Advice

    Hey Guys, I'm planning on replacing the driverside floor support on my 73'. Has anyone done this before, or know of a good build forum involving this? I need to cut open the bottom of the torque box in order to get out those spot welds holding it onto the frame, but if I do cut the torque box...
