Ok that is not what is considered a cable shifted trans, and it does have the late style NSS. The trans case I have is just the empty main case only. No tail housing or internal parts. I'm thinking you should be able to swap all the internals, and tail housing from your V-8 trans to the slant six case. However I am more familar with parts swapping on 904's, so I won't guarantee the swap. Maybe someone else could elaborate.
