I know this is an old topic but I did finally retrieve my PHS and since you asked me to check what it said about Decor group I thought I would let you know. I do have decore group listed on billing sheet. I do have all the items listed in the group on my car except I have Rally II upgrade option #454 instead of the Dlx wheel covers.
I am curious about the pedal trim plates, any way to tell if they are original? part #'s on the back or something? I will take them off and look if there might be something to see.
Also curious that I have Radio-P/B (opt #382) and Power antenna (opt # 381). Wouldn't option #383 (AM and elec. antenna) do the same thing instead of splitting it up?
