Don't like to through cold water on an intuitive flash, like
using two ski racks, but the fact are left "hanging" in the
"balance".


Since the C.G. (Center of Gravity) of the hardtop is at the
rear corner of the window frame, and presumably that is
where you would fasten the "first" ski rack, the problem is:

The rack at the rear of the window has ALL the weight, as
would a separate pulley system.  The front rack would have
no weight to lift, and would only be of value in creating an
angle backwards.  This may cause the rear mount to try to
slide forward on the stainless trim.

Using just one, with enough double sheaves pulleys, or a
winch, to reduce lift load, allows the top to hang straight
and horizontal.  It doesn't even tilt with a seat belt sling
and one swivel pulley.  It will, however, rotate if pushed.
Since I don't push it, it isn't a problem, but a simple
nylon rope tie-off from the top to the beams would prevent
that.

Steve.

BTW:  A couple of square aluminum tubes, pop riveted to a
center joining plate, some cross pieces at either end of the
longitudinal one, and some "J" hooks bent on threaded rod
through the cross bar is a simple lift fixture.  Could draw
it up, if you want, but a simple seat belt works fine, and
folds up for storage, as the hook-pulley are raised to the
ceiling for the better weather.

This whole job of connecting, releasing and raising the top
takes about 5 minutes.  A little more time and two people to
put it back on.  I'd recommend lowering to floor, releasing,
and manually inserting points in rear and clamps.  The
actual attachment is a two man effort for guidance and
rotation requirements.  If there are two available, manual
removal and transport to the floor under the pulley is more
secure, as the top needs to rotate to release properly.  It
can be done with one, but you've got to be careful of
swing.  I've never been able to park my car exactly centered
under the pulley.  Less problem on removal than
installation, regardless of lift hardware choice.
