I did the manual steering swap on mine.

Borgenson steering shaft is telescopic and eliminates that crappy box joint on the factory shaft and not to mention tightens everything up feel wise

I bought a remanned manual box and of course didn't come with the pitman arm, got lucky and found an NOS one after a month of searching

If you don't have one already its a great time to add the steering box frame brace while you are in there

Enjoy the arm workout, its fun with a 440 up front
