Identify What This Came Out Of

I think the ad is wrong! 1964 and 1965 A-bodies with 4-speed transmission did not use a slip in shifter. Factory 4-speed cars has a chromed Hurst shifter bolted to the shifting mecanism with two black phophated bolts with 9/16" head. In 1963 there wasn't a 4-speed tranny for A-body cars.
