#2 looks like it is on the other side of the wheels. I don't know how you could get a floor jack in that location even if there was something to lift with. And I wouldn't put the jack stands there to support the vehicle since you would have to climb under way too far to be safe to put them under or take them off.drboom - Here's what little is shown in the repair manual for Pacifica hoisting.
Locations '1' obviously are the normal pinch weld frame locations.
tsax6010 Thanks! I just ordered two of those pinch weld adapters you pointed out.
Locations '2' are your only alternatives. I'll have to get under my van to see exactly what is at those locations. I need safe locations to lift the van and also safe locations to place my jack stands.
The pinch welds are pretty wide - maybe there is enough room to lift with the floor jack and then put the jack stand next to it before repeating at the next location.
