Automatic column shift linkage.

Yes --- the shift linkage is different when comparing the Abody 727 versus the Abody 904. I had a 1971 factory 340 Duster with column shift automatic, and during it's life, a previous owner had swapped out the 727 for a 904. The 727 shift linkage remained and was modified to work on the 904, but the function and engagement was not as smooth as with the 727. There were some older threads from years ago on this website and on Moparts with pictures detailing the differences between the 727 and 904 shift linkages. Search the websites and see what you can dig up. Good luck.
