As you can see the white w126 is almost gone. I've harvested everything I might need for my black w126 in the future.

My issue is the rear springs which prevent me further disassembly. My spring compressor is not rated for rear springs.

Is there a safe way to release the spring tension and cut this section of the body in half?

Seems to me the springs are no longer compressed.
You should be able to pivot the rear trailing arms and remove the springs.

Seconded on what Alec said. The shocks, subframe, and differential keep the springs compressed. With them gone, they should be totally uncompressed. If you can't tip the trailing arms far enough to drop them out, loosen the subframe bushing bolts a couple turns and they should simply fall out.

Yep, there was no tension on the springs. They fell right out.

Anyone need this subframe, 75 bucks. Speak now or forever...
