If I have to pull it from the top ?

I pulled the /6 in my Duster out of the top with the transmission attached. You definitely need an engine leveler to do it. Raising the rear of the car would make it easier, although I didn't. I forget which points I used, but as long as you make sure that the chains are tight between the two points and there's no chance of the hook sliding on the chain it should stay pretty uniform. That last bit is key, if you do just use a single length of chain be sure to put a "loop" in it with a bolt to keep the hook from sliding, or the engine will end up on its side.
