What year and model used adjustable rocker studs? Can you still buy these new or are they junkyard only? If I went to the yard to get them would I be able to tell them apart from non-adjustable ones? I read somewhere that the top threaded portion is different in size for the two M10-adjustable, M8=non-adjustable. Is this right? Thanks.
