i bought a 87 turbo with a blown head gasket and i am planning swapping the rear into my 90 n/a when i get install my coilovers and swaybars. will this rear bolt right in or will i need to use the 87 axles or anything like that? i tried searching but i couldnt really find what i was looking for.. i just want to make sure i wont run into any problems when swapping this rear.
