Hi Folks I've just bought a Clarke CES500 engine stand. It should take the weight of the engine (227Kg). It all looks very good. However I've got a snag.   Where/How does it attach?   Does it really pick up on the engine/gearbox bolts/screws. These are 5/16UNC - they look mighty small to me.   I can use a starter motor hole (3/8").   If it is the 5/16unc - where does one obtain bolts long enough. I see that Moss only go up to 3" I can imagine Wickes doing Hi-tensil
