NOS Square Mesh AC A86CW Air Filter
 

Here is a very vintage piece complete with the original square wire mesh style element. A86CW seems to fit a number of GM applications from '59-67 although I couldn't confidently confirm which ones. New condition with a very tattered box. Looking for $50 plus shipping or best. Pics below:
