There are all kinds of articles written on this subject and I remember
writing one in the 80s. I have done both and strongly favor the lower
method. I've done the lower way about 5 times. The once I did the upper way
it scared the bejeezus out of me.
The from the top requires a lot of head room with the engine way up in the
air to clear the car. The tranny is generally attached and it is a long
piece to get up and over the body with no damage.
The lower method keeps everything relatively low to the ground and can be
done in a low ceiling garage.
I hike up the body with a hoist attached to a chain bolted to the body with
the cross member bolts (actually similar ones from a hardware store) screwed
in from teh top into the same holes. I leave the wheels on the cross member
and just roll out the cross member supported on a jack. A motorcycle jack
would work well I assume. I have one now but have not used it. I always just
used a floor jack, but I didn't have the MC jack at the time. Next time I'll
try it.
