Can the driver's side AC ductwork be removed without pulling the whole dash? Installing a Vintage Air System and do not want to pull the whole dash again just to get to that 1 outlet.

 

I have replaced the left side AC duct on a 70 Cutlass/442 by removing the plastic duct work that runs on underside of dash. Only remove the plastic duct piece that is from steering column over to the left side where the flexable duct connects. One other suggestion is to also remove the front seat or the drivers side bucket seat, it is a heck of a lot easier to manuver your arm up to the back of the duck in the dash. I know that first hand many times over!
