Mbx7 uses shorter arms than the mbx6. .. the front will most likely not work since you have to use the mbx7 steering rack. . The steering posts are spaced apart different between the mbx7 and 6
The pins and inserts are totally different on the 7 as well.. the 7 uses a " captured " pin opposed to the 6 uses a screw type pin with incerts with holes that allow the pin to go all the way through them
