it will be easier to set you front shackle angle with the motor in it as well. You will need the wieght to mash down on the springs to help you get the proper angle. The best way I have found to do it, is to tack on your "fixed spring mount up front, and use a piece of 2x4 that will fit between the shackle. Using a jack on both sides of the truck, let the truck down onto the 2x4, with the 2x4 being sandwiched between the spring eye and the frame. Be very carefull with the jacks, and have jackstands raised very close to the frame, but not touching it, in case of a fall. once the wieght of the truck is settled onto the springs, then flip the shackles up to the frame to figure out where to mount the frame side of your shackles. I'm sure there are many other better ideas, but that has worked for me on many of my one off rock crawlers. Good luck!
