[Fulton 1]

Can anyone confirm whether the Z/28 radius arms themselves (minus the inserts) are different from what would have come on the ZL1 stock? I've got the 23105018 and 23105019 Z/28 parts sitting here, but I'm contemplating on just swapping the inserts into my stock ZL1 arms. No need to replace the whole arm if the inserts are the only difference...
