I have an old scissor jack I picked up somewhere. That's low enough to under the frame when the tire is flat.

To fit on the bridge, the jack stands need to be kinda small. I have some smaller aluminum one's that will fit under there without raising the car up too much.

But, I really don't use jack stands any more. I have a 6' piece of 4x4 fence post that I slide under the car from one side to the other. That sets the frame at about ride height. To go higher, I put additional pieces of 2x4 or 4x4 in place.

You can also put pieces of wood under the foot boxes at the front, and under the outrigger, near the rear of the door.
