Safety ?
 

I want to use 4 bottle jacks to jack up my car from the jack points under the car. What is the best place to put Jack stands for safety? I'm doing front end work.

Using bottle jacks to support the car is foolhardy at best . . . just get some good jackstands . . . you're worth it. As for positioning, there are usually jack pads under the chassis visible as circular or squarish metal pads. Otherwise, I'd look for a reinforced crossmember as a stand positioning point, and have them placed as far outboard as possible. Double check with a "shake" test by giving the car a shove and see if there's any movement.

I have both I just want to know where to place the jackstands
