i need more flex. "coils"

[Destroyer]

I have coils in the back of my Bronco "wildhorse" they are stiff, it uses a stock Bronco front coil and xj coils will work too.
I have no tail gate and I don't have a spare tire at the time so I don't have much weight in the rear so I'm looking for a very soft/flexy coil. If it is a Bronco coil it will need to be at least a 3,1/2" lift coil or more, I can cut off what I need to get the right lift. I'm not sure how long the xj coil would have to be.
I'll measure my compressed coil length when I get home.
What would be a good coil? OME?
Let me know, thanks.

Compressed length of my coil is 15 1/2"

What brand are th tj coils? Are they the same shape as an xj coil?

I have a pair of brand new 5.5 inch XJ coils but they may be too high.
