ZX estate rear suspension

[Col]

Does anybody know whether the rear axle for the Xara is a straight swap for a ZX? Also are the saloon and estate axles the same? In the same vane, will a disk/abs Xara rear axle be compatible with my at present drum braked non abs ZX or are the brake lines etc re routed? My ZX rear axle is making terminal graunching noises.[?]
