Chevrolet rolled up option totals only where the option was specifically listed. For example is it correct to state only 116 Camaros were built with CE1 Headlight Washers? Of course not-it was included on each of the 37,773 RS cars. But as standard RS equipment CE1 is not listed on docs for them. Other options such as D96 [5,176] are the same-listed and counted only when specifically ordered.

ZL2 was included with COPO 9560 & 9561 [not listed on docs] and I doubt it is included in the 10,026 total. COPO production was low, maybe 800-900 units. ZL2 was a mandatory option[listed on docs] for Z10 & Z11 so that reduces the total to around 6,000 units. By the time it became available almost 84,000 Camaros had been produced. Based on engine production data about 4,500 Z/28s had been built 12/31/68 leaving 15,800 that could have been ordered with it. SS production was probably more linear [14.4% total] perhaps about 19,000 non Z10/Z11 SS cars.

So that leaves about 6,000 hoods distributed over 34,800 units; 17.24 %. Maybe 2,724 Z/28s and 3,276 SS cars. And that assumes equal distribution.
