Looking at a lot of the period Ads found in mags of the day. Chev listed the cars as a ,,,,
'Camaro SS with with Ralley Sport equipment' 68 Ad-"Some cars fake it. These make it."
'Camaro SS sport Coupe' 68 Ad-"The resemblenace is more then coincidental" Car clearly has RS option but not mentioned?
'Camaro SS convertable' 69 Ad-"Camaro SS...and friends" Pace car ad,,,Z11 content included RS eqipment...
I think they were more obsessed with convincing prospective Customers that could not swing a Vette that an F body would suffice.
The answer to this question is a matter of preference,,,as I always say,,,any one lucky enough to own a SS/RS, RS/SS, Z28/RS, RS/Z28 is very lucky and way you name it,,
68 SS/rs 396
69 SS/rs 350 LA Z11
