All these trans cases are the same part # except tha V5MT1-4 that'd in one year of the M.S.
The V5MT1-6 came on 3.0 24 valve 95-96. I believe they were put in 3.5s over in OZ. That model had different / smaller / maybe conical Counterbalance shaft bearing.
89-95 used the same Cuon.Bal bearing. Parts may be harder to get on the 6.

These are a heavy truck transmission , so I would think it would hold for regular use.
If your gonna drag race than no ,,,mainly case the jump in ratio from 1st to 2nd is too great and would be practical for that purpose.
