If you look at the standard (blackwall) tire & jack sheet (UPC 10, sheet A2), the coupe used #3949506 sticker, and the convertible used #3949513, and the spare wheel was installed with the outer face DOWN, and the jack base was installed with the top side DOWN. This sheet is for the standard equipment condition, which was blackwall tires.
If you look at the PW7/PW8 whitewall/redline/RWL tire & jack sheet (RPO PW7/PW8, sheet A1), the "model" block states "12300-467", which specifies the convertible body style, and that's what's shown in the illustration, using sticker #3949515. The illustration shows the spare wheel installed with the outer face (and the whitewall or redline or raised white letters) UP, using the added retainer #3929976, and the jack base was installed with the top side UP.
For the "SS", look at RPO L-48, non-illustrated parts list (sheet A2); under UPC 10, it says the spare wheel assembles the same as RPO L-35. If you go to RPO L-35, non-illustrated parts list (sheet A3), under UPC 10, it says the spare wheel assembles the same as RPO PW7, which specifies sticker #3949515.
