I don't know about driveshaft length differences between autos and manual trucks, and 2nd gens use a different transfercase that drops on the wrong side for our trucks. You can still use the 2nd gen trans though, just be sure to get the bellhousing, clutch hydraulics, and engine to bellhousing adapter plate. The clutches are the same. You will need to bolt up your existing NP205 to the NV4500. 1st gen manuals have a 29 spline t-case input, not sure about the autos.
The other option is using the "Advance Adapters" conversion bellhousing. With this bellhousing you can use 1st gen hydraulics, and it bolts up to your existing engine adapter. You also have to shorten the front bearing cover(supports the throwout bearing too) snout to make this conversion work. Its pretty straight forward.
Good luck
