I hate to tell you this, but in '64 the 3-spd was no longer the standard transmission with a 409 engine. The 340 was available with either the P/G or 4-spd, but the 400 & 425 were only available with a 4-spd. The 3-spd was still the "standard" transmission in all models, including the Super Sport, but only with the 6cyl or one of the 327s.
The top of the console has a separate metal plate where the shifter hole normally is, but on this car, it would be a flat plate with no hole. So, the entire console is not different; just that one piece.
I still vote to preserve that piece of history as-is.
........IN fact, I'd like to document the car before it goes anywhere else or has anything else done to it. That car has a lot to offer from a research point of view.
If you're interested, I'll send you some forms and put you to work
