Yea i think they do vary a bit though, i know a guy who had one from someone and from memory there was a couple of parts that needed to be notched/scalloped out so the arm’s didn’t touch when they moved, but they wernt done so the arms bashed as they moved and he had to take it all off to get re done ect. Not to mention the reputation people like mk motorsport has for taking money for bits that dont get delivered, or not at least for several months after they are promised
