What yoke do I need to purchase to make the 4l80 work with my 4l60 driveshaft?

From what I've found I just need a 32 spline 4l80 yoke with conversion 1350 u-joints. Is that correct?

Does the driveshaft need to be shortened? I keep finding differing opinions on that.

Does the output speed sensor on the tail section of the 4l80 need to be wired into the PCM?
According to the LS1 trucks write up all you need to do is repin the 60e connector. Is that the only wiring change?

 

I'm not sure exactly which yoke you need... but i'm sure you can easily find one at ajunk yard out of a 2500. The driveshaft will need to be shortened about an inch and a half for the swap.
