If you post this question on pirate they'll treat you like a dick
If you don't have a sals or don't know what it's off ask that question
If you are up to/capable of doing a front sals conversion you should know the radius arms are the CHEAPEST part and interchangeable (to suit the housing of course)
OBC was won many times on 'upgraded' rover Diffs. But ya pays ya money and gets what ya want......
