I agree with redmodelt, no spreader is required for the front spring. I put a block of wood between the axle and the shackle, then jack the axle till there is no pressure on the shackle. They almost fall out (or in) then.
If you are trying to remove the shackle, it must be worn out and so, loose in the bushes. There should be nothing making it tight if you have taken all pressure off it.
