ya um i helped do this sas. there was like 4 guys there, 2 of them already sas'd there own trucks. and the axle was sitting ready to go with the steering and leafs all on it. it was basically a bolt up job minus cutting the crap up. 5.5hrs believe it. in my driveway. minus no shock hoops or shocks but thats it.
Once again, the time it take to do an SAS includes all work done before or after.
