Question about 94-95 and 96-98 spindles

Ok, as many of you know the 94-95 spindles are different than the 96-98 spindles. if, just for this example, you own a 95 GT. would swapping in the 96-98 spindles offer you an improvement in anything? I mean the wheel wells are the same dimensions, what about the A arms? the k memeber are the same, jut different motor mounts right?

I dont even own a 94/95 mustang, but owning a fox, and looking to do the sn95 brake swap, i have began to wonder. since us fox body guys shouldnt really use the 96-98 spindles, can the 94-95 guys use them? would it render any improvement? possibly in handling?
