Look at this guys ad for a 1967 Z28 original powerglide car? What will they come up with next!!!!Heres a quote from the ad:
""The trim tag or “cowl tag” has an M Code for Powerglide automatic, in addition to the 4L Code for 302 Z/28 Engine. It is thought that all Z/28 Camaros were equipped w/ manual 4-speed transmissions. Seller has pondered installing a 4-speed Muncie manual transmission, but then the transmission code on the trim tag would no longer correspond. Nevertheless, this may be the only known 1967 Camaro coded L for Z/28, in addition to being coded M for a Powerglide transmission on the trim tag"
