X153 Do it right the 1st time you'll thank everyone in the end.
I've done several different locker setups, don't like airlockers they will let you down one day and it'll be when you want them the most, I love Detroit's, Aussie's are great, had no issues with my Lockrite's (except for that scary moment when they do unload), and ran a welded 3rd on the street forever and had no issues at all (if it is welded right you'll snap an axle before you ever break the welds). There are several good welded axle buildups here, Willy Mammoth just did a real good one for the Amigo that is bulletproof, bombproof and may even outlast the human race.
