Drivetrain Donor Selection

I have a 1998 Tahoe 2 Door 4WD with the NP246 Autotrac transfer case and I am trying to figure out which donor vehicle I should be looking for so I can use at least my stock front driveshaft and hopefully the rear as well. From what I've read so far it looks like a 1999-2002 1500 Silverado / Sierra or Tahoe / Yukon that has the NP8 option(np246) will have the same output shafts as the tcase that's currently in my truck. Can anyone confirm or deny this? I am also curious about the wiring for the dash switch as well.

I've been wanting to swap my 5.7 to a 5.3 or 6.0 for some time now and now that my tcase is going out(which is $1000 alone) I figured I can justify spending the $2500-$3000 it would cost for a complete salvaged donor truck from a local salvage auction. Then I'll be getting engine, trans, and transfer case, plus any odds and ends that I may need off the donor.

Any input would be appreciated.

My 2001 Silverado has the 5.3/4L60E/Auto Track Transfer Case (I believe NP246), I'm pretty sure your info is correct.

NP8 = 246 right?

From what I've read that is true. I have heard, though, that different years of the NP246 have different output shafts and possibly different encoder motors and therefore different wiring.

you could prob use the yokes off the doner but still use your drive shafts
