Somewhere on here is a post of mine from a couple years ago. I made this hoist cradle from galvanized pipe, a garden hose hangar, and some hardware I had in a drawer. Foam pipe insulators and a piece of soft carpet protect the finish. The hoist hooks into a single eye bolt on the center pipe. The two pipes cross and are conneced with U-bolts. This allows you to adjust the CG to get the balance right. The carpet pad pushes down opposite the hoist hook and the whole thing balances perfectly. The garden hose hangar provided two bows to reach under the top. A hitch pin allows the bow to be easily removed and inserted into the cross pipe. I can easily remove the top in seconds. When lowering it, the single hook point allows me to carefully steer the top pins into place on the windscreen and door pillars. It's not pretty, but is super strong and works a treat.
Note that my Coupe does not have a pin protruding from the base of the rear window. I would imagine with any hoist arrangement that is the most common danger area.
