Your friend will need to buy extra rubber blocks because the Quickjack's touch-points are the frame and the Model A frame is high off the ground relative to a modern car.

I use my Quickjack on a '57 Ford and an older Corvette. I don't use it on my Model A's. I do find that when the Quickjack returns to the floor, it tends to "crab" sideways about 1/2" so you must recheck the lift points before bringing it up again.
