XE (with the Coil spring rear is) is the same as XF, EA.
With the EB onward, there are small changes. Lower control arm bush is wider on the EB housing, but the bushes can be changed to suit accordingly.
Also, the connection's to the tail shaft may vary.
Everything up to EA used the old U bolt connection, but the EB onward had the 4 bolt flange connection. The easiest way to overcome this difference is to install a EB tail shaft, they range from $20-50 S/H, but is a worthwhile upgrade.
Hope this helps.
