Can't remove spring, need advice

[DarkoNova]

So the only things you removed from the subframe are the lower control arm and the shock? If it's a stock spring, just undoing the castle nut for the lower control arm should have allowed the spring to shoot downwards from the frame. Is it basically just hanging in the frame? Look under it and see what it looks like. It's probably rusted pretty good if it won't budge.

How does it appear to still be under pressure?
