I finally am getting the D30 Conversion done on my 1971 CJ5 retromod! The axle is finally rebuilt (by a shop) and now under my frame. I'm getting ready to replumb the brake systems and have some questions that I'm hoping you guys can help me with. I bought a new replacement master cylinder and it matches the original one that came with the Jeep. Unfortunately, last summer when I took this all apart I didn't take enough pictures of the import spots, one of which was the Master Cylinder. As you can see from the pictures, both chambers are the same size and volume. Does it matter which one is plumb to the front and which one to the rear?
