In what way did the first shocks not fit? If they came from another 4x4 torsion bar Ranger, they should fit yours.
If your torsion bars are maxed out, of course you only have room for travel in one direction.
You need to be replacing your shocks with STANDARD replacement shocks, NOT lift shocks. This has been covered here hundreds of times. Longer shocks are going to let the front suspension droop beyond design, binding the ball joints, tie-rod ends and CV joints. If you're not happy with the amount of travel in one direction, don't max the torsion bars out.
