Exact reproductions of the original A-body overflow tanks used in 1970 & later, as well as dealer retrofit for earlier models. Also, ideal for custom applications & transplants. TA 2053A is correct for build dates of January 1970 & later. This is the same tank most commonly used with the retrofit of 1969 & earlier Skylarks. TA 2053B is correct for 1970 model year Skylark & GS with build dates up to January 1970. Not correct for full size cars.
