30a jack points

[Walt Ebie]

Need to jack up my 30 to 'relax' the springs so I can apply some oil. I understand, from an old thread, that I'll have to jack the car up by the frame rails so the spring can relax. So where is the jack point on the frame you use when you do this? The car has engine pans so I'm not sure if they can stay on or not while jacking the car up on the rails. Suggested front and rear jack points would be a big help.
