How to do this? I see new output shafts for NP 203 for GM and ford , I am waiting to hear back from Mile marker. Difference to Dodge must be output spline? Use GM front yoke on back shaft?

Also why no locking hubs avail, 75-79? Avail 74 back and 80 up..must be same/similar parts in hubs ?Or not? one suggestion was find 80 up dana 44?

DNE made a kit for this conversion , hoping someone may have a parts truck with one on it? Suggestions welcome ? If you have unlocking hubs on 75-79 probably has something in 203 too. Unlocking hubs and locking 203 ,everything is still spinning on highway.
thanks for any comments from anyone who might know about all this,

Not really sure what you are looking for but here are locking hubs for 1956-2004.
