It'll work,but not really period correct for the 69 Camaro or 70 Chevelle.
As Chris mentioned,it has the later issued #891 elbow that started appearing on the original vintage 1971 ZL-2 equipped Chevelle aircleaners,but there's no thermac pot on the snorkle,like the original vintage issued 1971-72's had.
The current reproductions copied the more popular 69-70 snorkle design,but used the last known elbow design as well,via 1971-72.
I think Ricks is a newly released reproduction that has been used some.
