Can someone please date this A833?

A 440 car would have been factory equipped with a "Hemi" trans with 18 spline input shaft. If it is 23 spline then it was a 318, 340 or 383 car.
I bought a trans for my 64 at a swap meet. I thought it was a good deal for $225. When I finally took it apart for a quick refresh I discovered that it needed more than just synchros and gaskets. I have at least 1G into it now. So be careful and if it was me, I'd keep looking for an A body trans.
