Looking at the 1968 Dealer Salesman Album,they show a 1968 Chevelle SS steering wheel with an SS396 emblem on it.
Looking at a revised 1968 Chevelle Dealer Brochure,they show the Same picture,with an SS emblem on it.
This is a later distrubuted brochure,so as CJoe stated earlier,I would think that the early cars received the earlier description,and later cas the later description.
The 1968 Impala & Camaro do not show any Steering wheel shots in their literature.

The Parts books say:
*Horn Shroud emblem #3925881 is for 1968 Camaro w/deluxe wheel w/350 & 396.And also 68 Impala SS w/o woodgrained wheel.

*Horn Shroud emblem #3925196 is for 1968 Chevelle SS.

*Canadian SD Beaumonts used the Standard emblem.
