I have 4 jack stands.
To raise my roadster, I do the following :
1. I jack up the rear using the pumpkin (differential), then place 2 stands under the rear jacking points.
2. This then allows me to access the cross member just behind the plastic engine pan to jack up the front and place the other 2 stands under the front jacking points.

Reverse process to put it back on the ground.
