As someone said theres a bolt hole on the top left and another spot at the rear right of the engine. Put a bolt through the chain and screw it into them. if you have air con i then put the chain around the bracket so it makes a nice supportive 3 point thingy. jhave a few shackles to play with and wa la..

Also its very handy to have a few jacks and some blocks of wood sitting around as you always find theres some shit unplanned thing that needs support or lifting etc and your buggered if you can move it by yourself from underneath so they come in very handy.

Also have some masking tape and make tags/notes on all the wires you take off so you can put em back later.

And enjoy!
