I am using some screw in eyelets. These go into my garage joists (2x4s). I have some aluminum (YEP ALUMINUM) storage hooks. I back my truck into my garage, unbolt it. Lift the back end up, put the hooks under, then do the same for the front. It takes me about 15 minutes to do this.
Initial I had some reservations using the eyelets and the aluminum hooks, but After I was able to hang from one with no bends, and no other issues, I figured FOUR of them can hold my top.
I have so much confidence in these, I drive my Porsche back in under the top... /forums/images/icons/cool.gif
A pulley system would be better, but 1) my garage ceiling is quite low (the upper is used for storage, and 2) my Blazer has about 1" left to fit due to the garage door header.
