I'm gonna visit the donor s70 at the PnP tomorrow and get the rear springs.
If I am *really* gung-ho I might get the front's too. In either case, I think I should at least pull the passenger side springs, but a pair might be a good idea.

Thing is... I'm not quite sure how to do it, so I'm gonna bring a set of spring compressors and a full socket set. I've only removed springs from the 120-series before. For the old ones, you just remove the limited straps, jack up the frame and lower the rear axle. This lets the springs fall out.

I'm guessing to remove the springs from a wheel-less s70 on a rack, I will need to:

1- compress the springs
2- remove the shock absorber
3- remove the lower spring retainer
4- remove spring and release compressors.

If I can just knock off the absorber and stand back, it would make the whole process faster - although not especially safer...

Any Advice here?
