I already had everything I needed. The heater was already bolted to a piece of strut, that is heavily lag bolted to the floor joists above. I have no idea why I over engineered the heater mounting strut, but glad I did. I had some 3/8" eye bolts, and slid an old axle into them. Had the cheap-o cable come-along, forgot I had it, hadn't used it in a decade. Dug it out and there you go. An old tie down works to grab the engine. No OSHA here... just common sense. Don't put your feet under a heavy load being hoisted.
