Amen, and Thank You, coilover,
One of my assistants was a friend/neighbor, and the other was a friend/professional mechanic/painter (whom I paid by the hour). They were skeptical of my decision, but the pro had formerly helped with a more tradional upwards lift (with only hood, radiator/housing removed).
We spend much less than 1/2 the installation/re-installation time (engine AND sheet metal), and we spent no $$$ hours dealing with paint chips from assembly/disassembly of front grill parts/etc (1954 trucks).
Two careful people are needed for this technique, and three people are better (my third person was cheap insurance: he was a careful neighbor who took instructions and did not even accept one beer after the job (we put up with the bad jokes he told during the job).
