You get a coat hanger and loop it 2-3 times around a small slide hammer weight and weld the loop shut. Toss on the hinges loosely on the car and put in the back of the spring towards the rear. Then you use your coat hanger to grab the other end of the spring and pull it forward til it engages over the hook on the hinge. Done. Doesn't work everytime but does most of the time.
Easy tool to make too.
