Personally, If this car was ordered with a performance drivetrain, i.e. solid lifter big block, I would leave it as original as possible. That being the case the lack of options could indicate the car was intended to race. On the other hand, if it is a 350 car or possibly even a q-jet bb, I would not have any problem doing this addition. Depending how correct a swap you are willing to do, because there is a rear console light on a stick, you would need a different dash harness. If that light function can be overlooked , then the swap becomes easier. You could also run your own wiring from the light to the door switch to come on when either door opens. Besides the complete console needed ( including front metal mounting bracket) there may be a couple of holes to drill. All my cars are console cars so I wil have to defer to others as to mounting. The last thing would be a duct extension to bring floor heat over to the driver side. My reply was done at the same time Steve above , so may have some redundancy.
