your gonna like this its 50" between back plates ??? atlas type as got rear diff cover .. the English was removed from the front of axle .. spoke to the rally shop about the diff & he gave me a catalogue of diff s you could request if you had enough doe when you bought a limited edition 3ltr Capri .. it seems looking at this catalogue you could pick everything down to the wheel nuts ... they even have a two speed auto box in there & a 2.89 diff .. advertised as great for interstate driving .. not for over here then ???
