I don't waste time!! As far as I know, all Packard transmissions from '35 and up have the same spline input shaft, which BTW, is the same as a 10 spline Chevrolet. There was a transmission that I believe was for the Senior cars that have 5 bolt holes, but I think they'll interchange, you just don't use the bottom 5th hole. Try and find a '35-'39 floor shift trans, and you can swap the tops with a little modification with the later year transmission's, up to '54.
