How do you put springs in a "bare" chassis, With no weight on it? I have seen a lot of pics posted of rolling chassis and mine is about to go back together. I know putting those big block springs in there is NOT going to be fun! Also does anyone put rubber on top or bottom of the springs, or just put them in?

You will have to use a spring compressor. You could build one or buy one, just make sure it is heavy duty and good quality, and use lots of lube. Alot of pressure could strip the threads. Just put them in without rubber. The rears sometimes have a rubber disk.

I second the spring compressor, autozone lends them for just the price of a deposit. Jim

Place a jack under the lower control arm and jack the arm up until the frame just starts to come off your jack stands. Lower it back down until it is sitting on the stands. Remove the upper and lower ball joint stud cotter pins. Loosen the upper and lower ball joint stud nuts. I like to take them all the way off and then screw them back on five full turns.

Now lower the jack so it is just not touching the lower control arm.

Now the tricky part. Be careful and think each step through.

Use a pickle fork to separate the upper and lower ball joint studs from the spindle. You will have the force of the spring helping you do this. As the nuts are still on the studs the spring will not be released.

Install a spring compressor (most good parts stores have a loan program where you can barrow or rent a GOOD spring compressor, do not use a Harbor Freight tool!). The best style I have found is the one that goes up inside the coil springs. Put a chain around the spring for safety.

Compress the spring with the spring compressor, to help in this take your floor jack and jack up the lower control arm, as far out on the arm as possible, until the car just starts to lift off the jack stands.

Once again be careful and think these steps through. There is a LOT of stored energy in the spring.

Now you have removed the tension on the upper and lower ball joint studs bolts. Remove them. With the spring now compressed, SLOWLY lower the lower control arm with the jack enough to remove the spindle and set it aside. Now continue to lower the lower control arm with the jack. Keep an eye on the jack alignment as you lower the control arm. You can always jack the jack back up put the upper and lower ball joint studs bolts back on and reposition the jack. At some point, if you have the spring compressed enough; the lower control arm will not be under tension from the spring. Remove the spring and loosen and remove the spring compressor from the spring. The dangerous part is over.

The article 6T7gto sent is it. This is the key statement along with the photos "The idea is to insert the threaded portion of the compressor down through the shock opening at the top of the frame." Then it's a one man job and no issues getting the springs on or off.

I would have never accomplished the job without this tip, I used several spring compressors and techniques but never got it close.
