    Default wrong transfer case!!! What is this one for?

    So I got a new (used) transfer case to replace the original (clutches shot) on my 2001 1500HD. I try to install the new one (I'll spare you the long story details) and it turns out they have a different size shaft coming out of the tranny. Both T cases are 246, all the plugs are the same. The new one has a smaller shaft. What vehicle did that come off? Can I get the T case changed to fit a bigger shaft?

    Okay, so I guess all 246s aren't the same. The one I bought is for a 4l60e tranny, mine is the 4l80e, different number of splines. Are there any other differences in these two cases? Can the input spline be swapped out?
