There was no specific option list for Sandman as far as I am aware, only whatever was optional on the base commercial or what came standard with Sandman at the time (eg buckets, console) or what was precluded because of the Sandman package (eg side strips, remote control side mirror). I don't think you could option power windows on luxury levels lower than GTS/Premier, so only GTS, Premier, LS, Statesman and Deville. They were standard on LE and Caprice.
