The rear will bolt up, the housing is the same but the shafts are a little longer because of the abs exciter rings. And the front spindles and other brake componets will complete a 5 lug conversion.
You'll need to swap the input shaft on the '94 t5 to a fox shaft, the '94 shaft is too long and you'll need a fox bellhousing.
BTW whats wrong with the rest of the car, why not replace the clutch?
