drive shaft mod for nv4500

[87v10]

How much mod have y'all done to the drive shaft with this swap? I'm planning to do this since i drive expressway everyday.

I just got done swapping out my sm465 with a nv4500 and the advanced adapter bell housing and i didn't have to modify the drive shafts at all. I'm using a np208 and hydro clutch.
