intake manifold casting # Question

[my124677n]

On a 1967 camaro with a 327 2 barrel, would the casting # on the manifold be 3877652 or 3910601.  I can't seem to find any of the 3910601's on e-bay or craigslist so it makes me think that Camaro's used the 3877652 and the data I'm reading on other web sites may not be right.  Anyone have an orginal engine they could look at and report back.  Thanks.

My "Chevrolet by the Numbers' book shows the 3877652 as the intake used for the 67 327 2 barrel Camaro, as well as other Chevy applications.
