Unfortunately, this Novak adapter that mates the stout TorqueFlite 727 to the added-on Dana 300 transfer case seems to be rather unique. It was the only one the late Lloyd Novak ever made, we're told. The current regime at Novak Adapters doesn't like the 727 trannies, and won't make an adapter. Advance Adapters recommends using an '80 through '86 case, which would eliminate the need for an adapter. Oh, well, at least we tried.
