I saw an Alcyone/SVX in a scrap yard when I bought my first Subaru back in 1999. My brother had helped me get my 1985 Toyota Tercel Wagon to the scrap yard and I asked whether they might have an overhead grab handle for a Subaru, since one for my wife's side was not standard (but the holes were there). I believe I actually sat inside the SVX for a while to verify that the fittings were nothing like those for my Impreza. It was sort of a sky blue colour, I seem to recall.
Eventually we ordered a handle through the dealer's parts department. They suggested it was ridiculously expensive, but I recall it was only about $25. Now I think about it, if there was one on my side (perhaps there wasn't?) I don't know why I wouldn't have just switched it to my wife's side.
(We actually saved the similar handle from the Tercel; it sits on a knick-knack shelf to this day).
