Yes they are 3.5k+vat at BARA,u do have to modify the beam and the group A diff mount is no good,there is a specificalkly designed mount for a 9" diff,I think u have to drill a hole in the body aswell to fit this diff mount.Kevin Sharp,breaking his escos in the parts section,he had the diff,now sold,he knows quite a lot about it.
