How do you remove the hard top from a Mercedes SL without any power?

Power is not normally involved. There are some crank hoists (and yes power ones) that you can purchase, which if you have a high enough space to attach them, then have straps that go around the top and lift it. But all that does is get it hanging up there! The carts they make for storing and moving them are very handy though. Any MB accessory place or Ebay for sources.

These are heavy suckers! 2 people please!

Basically same as lowering soft top.

Release the rear securing latch, using the lever behind drivers door.

Release the 2 twist secure point up front, using the separate handled provided to do so. (Commonly tossed in glove box).

There may be some wires to unclip on the passenger side, if you model has rear window heat or such).

One person each side and up she comes! Sure, there is a rubber gasket on front and back that may be a little sticky. I recommend the 2 people agree to lift together, and then walk together with it toward the rear of the car in one motion....you want to avoid bouncing or putting it back down on the car paint.
