its not a bad idea. You don't want the car to fall on you in the install!!
I just used a piece of firewood
I am sure you have some up there in canada
Good luck on the install. If you need anyhelp, you know that we are here for ya!!
btw: I installed my shocks and springs today. It looks pretty sweet (well, in the back because the front is sittin' 2 feet high in the air on cinder blocks!)
later,
