The bar coverings are pretty much interchangeable as far as I know.
Porsche used up the last of the brushed steel ones on the first 1978
SCs, since they tend to use up the last of the parts bin that way
after a model change. Should be do-able.
    Personally, I think this look only works with all the steel trim,
the window surrounds and door handles, and even then it depends on the
color of the car itself.
