Karl,

I would advise doing whatever you need to feel safe and have enough access. Jackstands under the frame to hold the car will work. No one ever complained of being too safe while working in their own garage. I often think about what I'm doing in terms of whether or not there is anybody around to help in case I do something stupid. I haven't yet, but the safety culture is ingrained into me after 24 years working in nuclear power.
