I think you'd be better off finding a Ford close ratio t-19 than using the np445. The 445 isn't very common, even in the states, and Ford made t-19s by the truckload. I'm pretty sure all of the adapter companies make stuff to mate these to chevy engines because it's easier to do than use anything from Dodge. Dodge stuff is kind of it's own brand of different.
