In order to make all those functions you're talking about work? In the Subaru world, swapping clusters from different years is pretty common; and even though they seem basically identical, in reality there are a ton of obstacles to overcome just to make half of the features work and that warning lights are permanently on. These are clusters from the SAME MODEL from the SAME MAKE, just different years... to swap in a cluster from a different make/model/era and have all the features that the Z32 never had would be extremely difficult, to the point of not not being at all feasible.
