I believe the physical interchange would be 62-65. Are you thinking of putting in an SS cluster with the ammeter? If so, are you aware of the special shunt required for it?

just be careful of the "clock" opening, the acadian clock fits in the same cluster but more of it is hidden . i know to make a chevy 2 clock fit all you have to do is exchange the face plate
