I am also in the process of putting the factory power steering set up in my 67 Dart GTS (383 4 gear). You can check out the build thread in my signature. I believe the posts regarding fitting up the power steering is towards the end (build is still in process). My engine block wasnt the original, it was out of a 70 C-body, so there was some work I needed to do to get this thing to fit.
