Unfortunately, I didnt purchase the Transfer case. It was in my 85 when I purchased it. I need to look around and see if the receipt is sncluded in file that was passed along to me. It performed flawlessly when in my truck with no problems. Im unsure if it has the HD shift spring installed.

Trying to put 4.7s in my transfer case. The donor case that had the 4.7s was a forward shift with a 23 spline input shaft. I tore down the case; harvested the needed parts and am trying to put them in my case. The problem is that the smaller input gear is on the 23 spline input shaft; I need it on my 21 spline input shaft. I have looked it over pretty closely and do not see how/where it would come apart. Google-fu came up pretty short also.
So - is it going to have to be a new shaft or is there a way to move the smaller gear from the 23 spline shaft to the 21 spline shaft?
