(hi jack) is your name really dick landy or just the user name? I figure its just the user name but Ive heard a lot about dick landy and just got done ready an article about him in a muscle car mag. pretty cool guy, would be awesome to have the same name.
on the subject, I suggest getting an aftermarket carrier, like a detroit or auburn posi. traction will be better and from what Ive read on here the stock 30 spline carriers are nothing more then a bored out 28 spline carrier which makes it weak around the bearings. aftermaket carriers actually use a larger diameter bearing so that it is stronger in that area.
