Mercedes w211 e class estate wagon jacking and support points

Hi Guys, air suspension completely dropped on this 2006 w211 estate wagon, haven’t got enough room to fit a jack under the rear; I can raise the rear right side slightly by raising the front right side but, I can’t tell which areas under the car aside from the jacking points (I need those for the jack) are strong enough to put axle stands underneath.Can anyone tell me where I can safely place an axle stand to support the car? Any advice would be a massive help. Kind regards Charlie
