I hang mine from the garage roof every summer as well.
I use;
4) eyehooks (5/16") and 2 sets of motorcycle tiedowns. (None ratcheting tiedowns, get a good set of "Ancra" brand, they will last you forever)
- Mount eyehooks into ceiling studs slightly wider than width of top (Drill pilot holes first)
- Hook rear tiedowns to ceiling eyehooks and rear bottom lip of Jeep top
- Hook front tiedowns to ceiling eyehooks and ends together under front section of Jeep top
- Suck her up to the ceiling
- use small amounts (4") at each tiedown, I find front / back until half way up, then switch sides and repeat
For the rear hooks at the bottom rear lip of the top, I open these up so I can use a 1" x 6" long piece of wooden dowelling to spread the weight across the 6"s. For the front, I just throw a little foam between the top and the straps once I have her at the ceiling.
When connecting the front straps together , remember to go OVER the rollcage, else she will seem REALLY heavy to lift.
