It's possible; for my Healeys, I put the QJ rubber blocks under the
chassis, then lower the rear springs and front A-arms on jackstands (but
only to get the axles back to ride-height, and I leave the QJ there for
safety). On my Mustang, I put the blocks under the seam welds. You have
the same problem with a floor jack, which moves as you lower it, but
it's not as pronounced.
