Looks much happier...I'm sure you are too!! That was fast... Spring is gonna be pretty special this year...
Use the chain bolt hole attach 6 inch metal strips on each side of hoist connecting to a pivot point on 4x4 bracket
If you could you take a pic of the setup without the cab and share, that would bolster the explanation quite nicely...
Made a long U channel from 2x6s and a 2x4 with all thread bolts it to hoist arm at chain hole to pivot. Rachet strap to secure it. Worked well for a one man show. Many times actually.
