incase it matters, unless you are specifically looking for a 1973/1974 air cleaner base, any 1973-1979 Pontiac Firebird 350/400/455 will all work;
these are getting to be tough air cleaners to find.
The differences are subtle between years, and all look alike, except for some 1977(?) model year air cleaner bases which used a different snorkle, if that's what it's called.
I think I sold my last spare this past winter, but I can have a look.

I have an air cleaner from a 77 Lemans if you think it might be ok for you.
I just want to make sure my Formula fiberglass hood closes without getting damage, Firebird air cleaner drops lower, Ian I know yours won't work but Thanks anyway ...

Did you ever find one?
I forgot about this post, but last year I "accidentally" (because I am selling off spare parts, and shouldn't really be buying anything more) acquired an aircleaner from a 1975 Formula 400.
