Post 37 in my build thread shows how they shouldn't be. Everyone had told me that with no weigh on the spring my shackle should be straight up and down. If they are over 90degrees meaning that they are forward of 90 than suppsoedly they may invert when fully flexed and then a load put back on them. however when I installed my new springs they were about 80 degrees forward. Post #73 shows how they were at first. After the springs having settled they are perfect.
