With a floor jack, I allways lift right under the crossmember, to the rear of it, just in front of the steering link.
If you jack in the middle of the crossmember, eventually, you will dent the metal there.

A foot long piece of 2x4 (inches)wood will keep the floor jack prongs from poking the crossmember.

When doing general work, I place a jack stand on each frame horn just in front of the A frames. I usually support the rear axle under the axle tubes.

I have not changed sub bushings with engine in the car, so don't have a good recomendation for that.

I've raised mine with a floor jack placed where you have your middle red mark and have never had any problems. I have never left it for long periods of time like that though.

OK. I thought that it maybe could be bent or something, because its not ment to be loaded under there.

Im going to do my front end with PST and Hotchkis springs, so i guess the car will be hanging a while on the jackstands, and i dont trust to having the stands just on the S/F behind the engine(under the floor). All jackstands ive seen is lightly U shaped and the S/F back there is flat and much wider.

I tried to jack the rearend on the frame next to the spring eye, but the car just started to slide on the jackstand and scraped of the paint. Little scary.
I also have brand new Hotchkis leafsprings to install aswell. =)

Thanks

When I am removing the rear end and springs, I jack the car at the differential then support it with jack stands placed under the rocker panels with a piece of 2x4 between the jack stand and rocker. This works well and gives me a little more room near the front spring eye.

Also use more than two jack stands -- better safe than sorry! I agree with the others concerning supporting the front ~~ I have a bent in crossmember to prove it....

Good luck
Joe

Thanks for the answers guys.

I guess that a 2*4 piece could be wood or rubber?

I only used wood 2x4's but if you have some very stiff rubber, that might work also.
