I was just curious. I have a 67 dart GT and I rebuilt mine back in 2005. I updated everything with 73-76 stuff: Idler, center link, pitman arm and all the other stuff. I put a 74 V8 K mamber in too. Originality wasn't an issue for me, I just wanted the most durable stuff Ma Mopar made. Turns out the bushings and tie rod kit was cheaper too. Yeaaah!
