I keep on going back and forth between the factory 12 bolt and a 9 inch,What do you guys think of the durability of the 12 bolt is? I have a fairly built up 402.I seems be doing fine right now but I am planning to go with a much wider tire out back.Is it worth putting money into narrowing the 12 bolt or just putting the money into buying and buildin a solid 9 inch?
