In hot rod or car craft they said the Ford 9 inch gets a lot of credit but the mopar diff is probably just as good. Its just the ford 9 inch has more fame and availability. The gm has c clips which is why people dont like them, if they come off, your wheels will soon follow.

thanks guys the reason why i'm asking is because im looking to buy a duster..

yeah buy it man. new engine, new transmission, you'll have yourself a car. There's a dude around here who's got a nice green and black duster. it's awsome and one of the few cars I like to roll with around here.

cool thanks again guys...
