Further to that ghost option - as stated by the original owner of my 66 Monaco 440 4 speed car (special ordered in Calgary Alberta with a 426 Hemi, but never so installed - most of you know the story), he DID order the car with 4 speed and
Autopilot along with AC and Sentinel, but since the factory didn't have the Autopilot option available with any manual trans cars, the Autopilot parts were delivered in the trunk for "dealer installation" along with the other options like the Search Tuner radio and reverb (which was dealer installed), Sentinel and Chrysler power antenna/map light switch (car was ordered radio delete specifically to get the Search Tuner). The Autopilot installation challenge was figuring out how to deal with the engage/interrupt switch circuit (found on the brake pedal) and putting one on the clutch pedal. He had planned to do all that and more, but with a new baby on the way and other challenges, life got in the way and those options never got installed. He wound up having to sell the car less than a year after he bought it.
Since I am restoring the car, I wanted to do it the way he wanted it (not with the Hemi though), and I have since figured out how to mount a reverse operating interupt switch on the clutch pedal. I used a momentary switch - so when the clutch pedal arm is up, it presses the switch and keeps the circuit closed, and when the pedal is depressed and the arm leaves the switch, the circuit is opened - worked perfectly on the bench! With the success of that mod, I will be installing Autopilot in the car, along with the Sentinel parts. That was a whole other project - I've studied the Chrysler dash harness, and figured out and modified a secondary Fury/Canadian Monaco dash harness to be able to use the Sentinel, so that will be fun. I can understand why that never got installed - what a job that was figuring that out! Many of the Sentinel parts came NOS from the original owner once we connected - he'd kept them all these years, and so I got them when we connected (another great part to the car's story). He was unable to find the Autopilot dash parts though, but fortunately I was able to find them from various people - super rare for Canadian Dodge Polara/Monaco and Plymouth Fury.
He also ordered the car with AC, but it was never installed due to it being a 440 HP engine (and originally ordered with 426 Hemi, but not fulfulled - that's part of the car's interesting story) - now we know from above posts that AC/4 speed might have been possible if the car was a 383, but it wasn't. So no AC dash. Parts were delivered in the trunk apparently, to facilitate an underdash knee-knocker AC box, but all those part were long gone. I've sourced a 66 Fury AC dash (I'm keeping the original dash in storage), and will be installing that in the car with an aftermarket AC setup hidden up under the dash, using the factory dash vents and Non-AC controls. Again, a lot of planning and research, but all do-able, so I will be restoring the car to what the original owner ordered and hoped to get - all except the Hemi.
You can see that the Chrysler Search Tuner and power antenna/map light switch were installed - the radio holes were simply cut through the radio delete plate with a hole saw, and a similar hole was cut in the dash for the antenna/map light switch:
