if you really wanna know lol..

did it on my buddys civic that has some major rear end and front end damage, basically the rope has a crank thingy that tightends the rope and you crank it, just park the car, per say if you wanted to move out the fender or try to straigten it, park the car sideways next to the tree, and get one end of the rope around the tree and the other end onto the part you want to move outwards...the one he has, has a crank in the middle and 1 hook on each side of the rope, so we hook one side to the fender, and rapped the other end of the rope around the tree, and just started to crank away and it eventually moved...but you need a good hugable tree lol......
