Only Satellite and Road Runner Decor Group cars, which used the Satellite interior.
All '68 RR HTs were Decor Group cars, it was optional on coupes.
I've seen one '69 RR HT (in the late '80s) that had the base interior, but I can't say that was its original interior.
All of my own '69 RR HTs had Decor Group and were original.
Decor Group was optional on '69 RR coupes.
The standard RR coupe interior was same as Belvedere, no medallions.
