Think I have found the K&N part number and the corresponding Accel Kool Blue filter number. K&N part# E-3180, Kool Blue part # KR1117. These filters are 6" O.D. x 4.5" I.D. x 1.75" high. These filters are listed for use on the Triumph Herald from 1961-1970. Not sure if it will fit the original Chevrolet dry style air cleaner until I receive it, but it looks real close. Will update once I get the air cleaner assembly.
