Use 2 beams instead of one like in the picture, and no straps needed. And add 2 boards connected to make a T, that is if you wish to lift it higher than with the way the engine hoist is connected in the pics. Reason to lift higher? So it can be loaded into a pickup bed if needed to haul it someplace or storage.
scroll to the last post with photos. And no strap needed there either if the wood was centered more towards the front of the cab. 2X6's work best.
