A couple 2x6s and some 2x4 scraps. copied a design from others here but use 2x6 for overkill. 1 lag bolt to tie the upper together and 1 bolt through the lower extension through the hoist eye (remove the chain). Used a ratchet strap to tie the rig to my engine hoist so I wouldn't have to worry about balancing it. I can get you some measurements if you want. All by myself
