4wd 4L60e output shaft differences

[Wunjo]

I have 2 output shafts form 4L60e transmissions.

 

One is from an 99 and the other from an 03. I didn't pay enough attention to which came from where. The rear planetary shattered so I'm using the best parts from each to make one.

 

I am pretty sure I want the one on the top. Would someone confirm it for me please.

 

The differences are the one on the top

   - The input end splines are shorter

   - The middle splines have a snap ring grove in them

   - It's ~ 1/32" longer

 

Thanks

   Do they have the same spline count on the back end?  While doing some research on transfer cases for my 03, I found out it has 27 on the input (Transfer case).  I believe older ones had more (like 32).  Not sure about the other differences you note.

Yes the both have 27 splines.
