My understanding is that you 96 Wizard and your 94 Mu should both have the same torsion bars (both UCS69).
The major differences between torsion bars on the Mu/Wizards came in the change from 2.8 (UCS55) to 3.1 (UCS69) powered vehicles.
The UCS55 had a shorter length and larger diameter torsion bar than the later UCS69.
The ride in a 3.1 Mu is noticably softer than a 2.8
Also, as above comments have suggested, see how you get on with just adjusting your torsion bars after fitting a winch. If you can attain the height you require (within the adjustment available) and the ride is still ok then no need to change.
