Well i just tacked up the front, and the shackle is sitting at an 85 degree angle towards the rear.  Is that an ok position.  that is with placing the front hanger flush with the cross member, and the short side facing forward.  It looks like it i push the shacke back any more and get closer to a 80-70 degree angle, it will hit the body mount.  I am going to look to set the rear angle around 45-55 degrees or so. 

Does this sound like it will be good for flex (running the 5" marlin kit, with 5" shackles up front and 5.5 in the rear)

i will get some pics up tomorrow!
