64 Dart

They didn't do 3 speed on the floor in 63 but they did 4 speed on the floor in 64 even with a slant.
Yup, and that looks like a factory floor-shift floor pan (not an aftermarket hack to convert from 3-on-the-tree) so this car looks to be a 225/4-speed. Worth grabbing just for the bellhousing, trans, factory Hurst shifter, and floor hump!
