Wow.I have seen a couple of royal plum LX SLR's and they had the stripes in silver.
The only Royal Plum SL/R I've ever seen is my own.
I have seen quite a few RPM Toranas and I hear that many RPM SL/R's and Toranas were painted in more fashionable colours in the 80's. One guy approached me once and said he had the same colour Torana and painted it red, I remember seeing a RPM hatchback that used to park under the bridge at McDonaldtown and the guy ended up painting it a dreadful green colour.
Yep, back then it was quite an unfashionable colour, I once went to a car dealer and asked how much I could get for my car and the first thing he said was, "Ohhh purple, it'll be hard to sell".
