I purchased my '68 RS Conv. over the Summer and am now getting around to replacing the steering wheel as there are quite a bit of cracking and chipping. My car has standard interior but the steering wheel is Deluxe (with RS horn cap).

I was wondering if the Deluxe steering wheel could be the original, even though the interior is standard. I've tried looking up what was included in the 1968 RPO N30 option (if it was an option) with no success.
