I have got to take the bike down to the dealer in a van tomorrow

. I've got hold of some ratchett straps but does anyone have any advice on the best place to attach the straps on the bike? Presumably two front, two rear. The two at the front up near the headstock with the front brake held on, and the two at the rear somewhere on the rear subframe? I dont have a paddock stand (yet) so cant use that to help keep it upright.
Thanks,
Ben
