Input drive swap....is it hard?
 

OK....I have a 1996 4L80e tranny with transfer case and a 700r4 tranny with transfer case. I need to use the 4l80e and the transfer case from the 700r4 together but I'm told I'll need the input drive gear changed from a 28 spline to a 32. If so is this a hard task? Or should I just try and trade it?
