I recently replaced the hood hinges on my 49 with no help.
I opened the hood in the garage and took a plumb bob and marked the location of three pickup points on the ceiling
None fell where there were any rafters, so I took some old garage opener support pieces I had and tied each piece to a rafter or straddled the rafter
I used some HF ratchet straps to connect the hood to the ceiling, To hook the ratchet straps to the hood I used some loops of paracord on the hood.
Put a little tension in the ratchet straps and loosened the shoulder bolts on the hinges, then did the R and R on the hinges.
I don't see when you couldn't put the hood on the floor and project some pickup points on the ceiling and do the same thing, then hoist the hood up and drive the truck underneath it.
