I believe on the 123 models...which have something like this for jacking up the car using the side holes.... that that is for jacking up only and that the jack stands are supposed to be used before you get under it... it puts the means of raising far enough from the LEGIT point under the body for the rigid jack stands to be placed under the car....and the weight let back down on them.... ( from pics in the 123 FSM )...
