2000halftontank

I own a 2000 1/2ton 4x4 silverado with a 5.3 and a 4l60e. I have a donor 2001 3/4 ton with a 6.0 and a 4l80e but its 2WD. The donor truck is complete, just a little wrecked. I still want to keep my truck 4wd. what is needed to convert the 2wd drivetrain to 4wd? and the 5.3 to 6.0?

you need to open up the transmission and swap out the output shaft, you also need to modify the cross member and drive shaft. do a search there is a ton of 4l80e swap threads.

so its going to put my transfer case back further. that means that both driveshafts have to be replaced.
