with the billet aftermarket carried they older style that had the hole you need a round price of metal, they use to come with them but if you buy them from ebay they wont so i use an allenwrench.

for the new style billet carriers they are kinda slotted like oem but you put in a 1/4" ratched extention and it works perfect. i honestly dont know why they cant machine the carrier like a locking nut so we could use a wrench!
