Dan, the used Dana 4.10 OEM gear set I put in my Duster (same housing as yours probally, 3.125 axle tubes diameter) looked decent on the drive side but I could not get a decent looking pattern on the coast side, I did have to have the gear set glass beaded to get the rust off of it before trying to set it up I tried sevral different depths and ended up leaving it looking like your latest one It is quiet and faster than the 8 3/4 was I agree with "Bucks up" Bob on running it the way it is now
