I jack mine up just aft of the red line. Yes it is caved in there from all the jacking, was when I bought it. My engine is out now, before I reinstall I'm going to weld a 1/4" plate on the bottom of the cross member with a couple of lips to grab the jack. I've had the car on jacks about 50 times, I'm hoping if I go overboard preparing a jack point I wont have to use it.
