Looking for a 404 back axle

[Noot]

To complete an Arnolt Bristol drive train I need a backaxle preferably with shock absorbers.
Can anyone help?
Can this only be a 404?

As far as I know the axle is specific to the 404 and 404X. The 401 does not have bracing added and I know to my cost the problems with that. The 403 has two sets of bracing, while the Arnolt has only the additional ring around the banjo. The 405 has different shock mounts and if you need a diff, a different ratio.
