alright, thanks for your help! Ill order that at Jegs, dont know why it isnt at Summit, usually they both have the same. The only thing i noticed about the auburn pro is that it says must use ford ring gear bolts for an open carrier, not the LSD because they are too long. Do you think the richmond gear install kit has the right length? Because they have a separate install kit just for the 9-inch traction-lock, and the other is for the 9 inch. Thats my guess. Thanks again!
