The jury is still out on whether there were any L89 Novas built. The ones being promoted as L89 cars haven't convinced the experts. Until somebody comes up with a legitimate build sheet, POP, factory invoice, etc. that has RPO L89 on it, I believe the doubt will persist. If there are any, they may, or may not, have come through the COPO network.Bob,
You seem to be one of the most knowledgeable historians on here. Is it safe to say that if an RPO wasn't involved in any type of COPO stuff and isn't in an assembly manual, then it wasn't offered in the car? If it isn't, can anybody think of an example where it isn't the case?
As for Asssembly Manuals, they're wonderful sources of info for things that made it into the cars. Unfortunately, they also contain all kinds of stuff that never made into production (V/8 engines and 4 speeds in 63's, for example). Conversely, some things that did get produced didn't make it into the AM's, especially if they were introduced late in the production year.
