This unit will also fit and work on a '55. It has an indent on the bottom for the '56 choke assembly which is not needed on the '55 application, but it will work just fine.
American made reproduction of the 1956 TBird air cleaner except that this unit uses a replaceable dry element instead of the original oil bath.
Features: polished stainless steel lid, durable powder coated base, replaceable air cleaner element, air cleaner to carburetor seal, cork installed with power stapler as original
