Your posts sound just like mine over the last few weeks. I have a eye bolt well screwed into the back wall of my garage that I use with a come-along to get projects into the garage. My first project was to get the old girl running because the seller offered to refund a third of the selling price if the engine is shot. Don't feel bad about posting pictures, I've been trying for 2 weeks and clearly suck at it. Good luck on your project.
Funny you say that, I've had the exact same thought about the come-along. Two fears have kept me from trying it just yet:
1) Wouldn't have a way to stop the truck if the cable broke (hence hiring that done)
2) Afraid I might pull the stud out of the garage wall to which the eyebolt is attached.
