With the Panda in 1st gear,
and chocks around the FRONT wheels.

I use a trolley jack on the centre of the rear suspension beam to raise the complete REAR of the Panda,
then I used 2 x axlestands - with wooden load spreaders on the 2 x rear sill / floor junctions (these have a large circular rubber bung)

with the car well supported on the 2 x stands( I used further trestles under the sills - in case of unexpected movement / failure)
