Here you go snafu. There was a double roof truss running right down the middle of my garage. That is what the ceiling eyelet is in. The wall eyelet is in a stud. Took a picture of the hardware next to a tape to show the size I'd say they're at least 000 eyelets. The hooks have retaining clips so the whole thing can be taken down in a few seconds. One day I'll put an electric hoist up, but for now the come-along will do. We're supposed to have a few days of great weather so I'll take a few pictures of it with the top up soon.
Here's a little update I made today. Gets it out of the way while not in use. The 2x4s act as spacers and give a little extra clearance. I added the chain for clearance while lowering the top. It took me 15 mins to put the top back on today. No complaints here!
