Since it is a low miles car, the body is pretty good, even the leather looks good, the door panels seem nice, the instrument panel will clean up nice and rarely has cracks in this model, the steering wheel looks good, and so on, it won't be that bad of a restoration. Plus the engine is low miles and spins and probably the rest of the drivetrain would need minimal anything. One of the sticking points will be the Autotemp since generation 1 controls are not readily available to my knowledge and were prone to frequent maintenance from others I have heard from. But while redoing the body and cleaning up the engine compartment, you might want to consider switching to standard a/c controls at that time plus the standard a/c evaporator and heater assembly and associated wiring and hoses.
I think it will be an awesome project. Enjoy!
