still looking for console information

Could have sworn this was covered in another thread. As stated above in post 2, the A/C cars with consoles are the "short" ones. I parted out several A bodies in the 90's, but all were 72 or later - saw several that way, console won't fit otherwise with the factory duct below the dash frame. No AC - regular console without the cut. Maybe something was changed with the duct setup after 71-72? That's what I observed. Maybe someone with a 73-ish parts book can say?
