no, they are sicurisssimo why? I ? happened to replace the manifolds, deformation of a golf 130 with those of 150 and the mod was not feasible for the different mounting of the wheel of the vanes.
nothing....the geometry of the 150 houses only in the manifolds of the 150(which also have a larger diameter)....so if you want to mount the coreassy 150 to the geometry of the 130 that you can't? even replacing the geometry of the 130 150 why? not the you can? secured to the manifolds.
