[AT] Neat jack idea

[Larry D Goss]

Uuh, be careful when using jack stands also, folks.  My SIL (attorney) has a 
case involving a jack stand (ratchet adjustable) that collapsed under the 
front end of a small passenger car.  The owner placed it under the wishbone 
of the front suspension (not a horizontal surface) and proceeded to work on 
the wheel nut so he could remove the brake disc.

He left a widow and three young children.
