<VV> Corsa VS Monza VS 500 air grill

[Padgett]

Folks, keep in mind that often GM serviced many different parts used on the 
assembly line with just one service part so the P&A only tells you what was 
used in service and then only as of the date of the manual which may be 
years later.. Similarly, the Service Manual was put together in the 
earliest production so misses slipstreamed changes.

You really need all four: Assembly manual, Parts book, Service Manual, and 
all TSBs/campaign notices/recall notices to have a good idea. Add to this 
component differences are often noted in the component manufacturer's books 
and not any Chevrolet book  (the complete Delco Remy listings often show 
one part number for "First Production" and a second part number for "Second 
Production").

BTW there also were often different elements (particularly brightwork, 
stripes, and insignia) used between assembly plants. Is it possible that 
one plant used silver grills and another used body color ones or that the 
change occured during a model run ?

Sounds like this level of detail is just starting for Corvairs, other 
makes/models have been doing it for years.
