Yes, you can just pull the 400/QT and bolt in the 400/20. You should have enough rear driveshaft length to not worry about swapping the rear axle either. As for the stock adapter, my brother has been using that drivetrain behind a buick 350 in his wagoneer for almost 10 years. I'd say just check it to make sure there are no cracks when you put it in and use it till or if you ever have a problem with it.

Also, if you are asking about using your same 400 and just changing the transfer case, that won't work. You have to change the transmission output shaft which has to come out the front of the transmission and requires it to be completely disassembled. Just plan on getting the 400 with the dana 20 rebuilt.
