Advise please 197/200 rear axle

Just wondering if there's a difference in the rear axles fitting on 197, 200 and the cup models or are they all identical.

Can anyone help please
 
All the same, except for the cup race cars which have a pivot in the centre so that each axle is independent.

That's not true, the cup racers use basically the same rear beam as ours but renaultsport replace the rubber bushings with a spherical bearing in a welded in housing.
