Bagging a 1980 Chev Dually

So I found a 1980 Chevy Crew Cab Duall 454 auto 2wd and I was wondering whats all involved in bagging it? Right now I think I'd just keep it on the stock 16s but eventually I'd like some 22s and to stock floor it. I have a bagged car now so I'm not completely new to this, just haven't done a dually.
