The factory docs and order form are clear: T42 is an add-on, very much like the cowl hood was on a Camaro.
Exactly like the cowl hood. Which didn't change anything about the main option on the 69 Camaro. A Z is still a Z without the cowl induction. An SS is still an SS without the cowl induction. A ram air III is still a ram air III without the functional ram air hood. How do I know? Because the invoices say it. Clearly spelled out 'RA'. There are many like that. Simply put, if your car has an invoice that says RA, it's RA. Talking heads of the future can't take it away if you have your invoice saying it.
