Nice! Ya someone told me alot of guys swap the whole k member so I ordered pitman and idler arm for a 73. Wrong... Haha the 72 was custom order and twice as much of corse. It should be here today though.
Yeah, all of the steering is still stock 72 stuff, including the k-member. You can tell quickly by the biscuit style motor mounts. You're figuring all this out though. I'll reply to your PM with more info. Congrats on the car btw. It's a really solid Duster - just needed some attention. It was disappointing to see how much it deteriorated since I sold it.
