does anybody know if i can put a NNBS (2007-present) front differential assembly in a nbs (2004 to be exact). I need to replace my carrier bearings and just want to have the shortest downtime and really not interested in rebuilding it. I found a NNBS front diff assembly with 24 miles on it for $500. so i need to know if the whole assembly case and all is interchangeable. Thanks in advance.
