     Jim,
Your suggested technique got me thinking of a variation to your method.
Use a breaker bar and box end wrench.  Jack the front end up.  Position
the wrench/breaker bar on the bolt at a 4 o'clock position.  Make sure
car is in gear.  lower the car to the ground and let gravity take over.
If this doesn't work there is always the neighbor's pet mule!

bye for now
