Is a 58K /6 904 tranny worth pulling for the hard parts?

I believe the only difference is case but dont quote me on that

/6 904 might have only 3 forward and direct disc in the drums...might as said

I hate to can it if parts can be used but it isn't worth pulling and storing if I can't use the parts should I need them.

I know to grab the speedometer gear assembly, the dip stick tube assembly and the tranny cross member if nothing else.
